Note: Please note the following warnings regarding the hazards associated with development systems.

Table 1 Safety precautions


| Warning: The DC link potential of this board is up to 600 VDC. When measuring voltage waveforms by oscilloscope, high voltage differential probes must be used. Failure to do so may result in personal injury or death.
---|---
**| Warning** : The evaluation or reference board contains DC bus capacitors which take time to discharge after removal of the main supply. Before working on the drive system, wait five minutes for capacitors to discharge to safe voltage levels. Failure to do so may result in personal injury or death. Darkened display LEDs are not an

indication that capacitors have discharged to safe voltage levels.

**| Caution: The heat sink and device surfaces of the evaluation or reference board may become hot during testing. Hence, necessary precautions are required while handling the board. Failure to comply may cause injury.
**
| Caution: Only personnel familiar with the drive, power electronics and associated machinery should plan, install, commission and subsequently service the system. Failure to comply may result in personal injury and/or equipment damage.
**| Caution:** The evaluation or reference board contains parts and assemblies sensitive to electrostatic discharge (ESD). Electrostatic control precautions are required when installing, testing, servicing or repairing the assembly. Component damage may result if ESD control procedures are not followed. If you are not familiar with electrostatic

control procedures, refer to the applicable ESD protection handbooks and guidelines.

**| Caution:** The evaluation or reference board is shipped with packing materials that need to be removed prior to installation. Failure to remove all packing materials that are unnecessary for system installation may result in overheating or abnormal operating conditions.

The board at a glance

  • This board is suited for double-pulse testing as well as continuous operation mode. The board has been designed and the components selected to reflect a typical, state-of-the-art induction cooking system based on a half-bridge topology. The main difference with respect to a complete system is the absence of a rectifier, filter stage and auxiliary power supply regulator stage. For this reason the inverter must be supplied with a DC voltage, and an additional low DC voltage (up to 20 V) must be provided to supply the driver IC and the fan.
  • The control interface has been designed so that it can be easily connected to the Infineon Boot Kit XMC1300 Microcontroller Unit (MCU) board1,2. Alternatively, it can also be connected to a pulse generator or to other digital circuits.
  • The board has been tested with input power up to 3000 W, with an input DC voltage of 250 V and an auxiliary voltage supply of 20 V. Users should note that the auxiliary supply voltage determines the cooling performance of the heat sink and fan assembly, i.e., the output power may be lower in case the axuliary power supply voltage is lower than 20 V.

Delivery content

  • The evaluation board EVAL-IHW65R62EDS06J contains the printed circuit board. This board is designed to offer the best layout guidance for incorporating the
  • IHW40N65R6 into a half-bridge resonant inverter. The gate driver stage is implemented on four separate daughter cards, each featuring a different driver IC model. Even though this approach is not the most common for typical induction cooking designs, particular care has been taken to optimize the gate driving loops, and therefore to minimize parasitic inductances. Thus the layout of the daughter cards can still be considered as a guideline for implementing the gate driving stage in a real application design.
  • The assembled gate resistors are selected for use with IHW40N65R6 and with a gate supply of up to 20 V in the IGBT on-state.
  • The evaluation board kit also contains the resonant coil that must be connected to the board. The users can connect different coils to the board to test different load variants. The electrical characterization of the evaluation board was done using the coil that comes with the evaluation board.

  • To adapt the circuit to application requirements, resistor or capacitor values can be changed to optimize the performance.
  • Attention: Before operating the board, make sure that a gate driver daughter card is properly inserted in the connector X2.

Power-up sequence

  1. Connect supply GND to connector X1- and supply VCC1 to connector X1+ with +20 V.
  2. The VCC_LED will turn on.
  3. Connect the JP104 of the Boot Kit XMC1300 to the connector X4 of the evaluation board, as indicated in Figure 31.
  4. Connect the negative terminal of the high-voltage power to connector X3- and the positive terminal to connector X3+.
  5. Connect one end of the coil to L1 and the other end to L2.
  6. Turn on the power supply with up to 270 V.

  3. Turn-off the other supply voltages (VCC1) and verify that the VCC_LED is off.
  4. Alternatively, connect the first output of the signal generator to the digital interface connectors X4.3 (low-side input) and X4.2 (GND) and the second output between X4.8 (high-side input) and X4.2 (GND). Make sure that the outputs of the PWM generator are disabled. Infineon-EVA-IHW65R62EDS06J-Evaluation-Board-fig-7
Connection of measurement probes
  • The evaluation board offers dedicated measurement points for the IGBT’s gate and collector terminal voltages with respect to the related emitter terminal. The test points are marked with the following labels:
  • VCE_LS: c ollector-to-emitter voltage of low-side IGBT
  • VGE_LS: gate-to-emitter-voltage of low-side IGBT
  • VCE_HS: collector-to-emitter voltage of high-side IGBT
  • VGE_HS: gate-to-emitter voltage of high-side IGBT
  • Assuming that the oscilloscope ground is connected to the ground of the digital interface (either the Boot Kit XMC1300 or the signal generator), the different voltages can be measured by means of the following probes:
  • VCE_LS: “high-voltage” passive probe (with attenuation of 100X or more)
  • VGE_LS: “low-voltage” passive probe (with attenuation of 10X or more)
  • VCE_HS: differential voltage probe (with attenuation of 100X or more and a a maximum common mode voltage >400 Vdc)
  • VGE_HS: differential voltage probe (with attenuation of 10X or more and a a maximum common mode voltage >400 Vdc)
  • In addition to the voltage measurements, the evaluation board comes with jumpers to measure directly the current of the IGBT flowing from/to the emitter terminal. The two jumpers, one for the high-side and one for the low-side IGBT, are placed on the bottom side of the board and are suitable to be used with Rogowski coil current probes, as shown in Figure 4.

Resonant load specification

  • The experiment results presented in this document were conducted with the coil provided with the evaluation board, and with cookware suitable for induction cooking systems. As known, the behavior of the power converter is largely dependent on the particular coil and cooking vessel that is used. In particular, the coil inductance, diameter, and distance to the vessel are important factors to consider in the design of an induction cooking system. The design of the resonant coil is not included in the scope of this document. However, in order to provide a reference for the results presented, the details of the resonant coil are shown below. Figure 9 depicts a coil with the dimensions and distance to the vessel that should be maintained when the latter is placed on the coil. Finally, Figure 10 depicts the frequency dependence of the series resistance and inductance values of the coil, without the vessel, and with the vessel positioned on top.Infineon-EVA-IHW65R62EDS06J-Evaluation-Board-fig-15

Usage of external software to control the XMC

  • The EVAL-IHW65R62EDS06J evaluation board does not include any microcontroller. The signals to control the gate driver, and consequently the IGBTs, can be either provided by means of a signal generator or of a microcontroller unit.
  • In order to set up and implement the evaluation board more quickly, firmware and a user-interface (UI) have been developed1 that can be used in combination with the Infineon Boot Kit XMC1300 [1] MCU board.
  • This chapter provides information on how to program, connect and control the MCU board.

Programming the Boot Kit XMC1300 board

  • The firmware on the XMC1300 MCU can be programmed by using the Infineon XMC™ Flasher tool [7]. The user must install the software and connect the Boot Kit XMC1300 board to the computer. Once the connection is established, the file with the firmware (provided as .hex) can be selected and loaded in the MCU by using the button “Program.”
  • Connecting the BootKit XMC1300 board
  • The connector X4 on the board has been designed to provide an easy connection to the Infineon Boot Kit XMC1300 [1]. A standard 10-wire ribbon cable can be used to connect the evaluation board to the boot kit, as shown in Figure 11. Please ensure that pin X4.1 of the evaluation board is connected to pin 0.8 of the JP104 port
    on the MCU board.Infineon-EVA-IHW65R62EDS06J-Evaluation-Board-
fig-17

Controlling the BootKit XMC1300 board

  • Once the XMC microcontroller on the BootKit XMC1300 is programmed with the provided firmware, it can be controlled by means of a graphical user interface (GUI). The GUI has been developed to provide an easy way to:
  • Select the right PWM configuration for each of the gate driver IC models that are provided with the board
  • Select and configure the switching frequency, the duty cycle and the dead time between the driving signals of the two IGBTs on the board1.
  • The main window of the user interface is shown in Figure 12. It consists of different sections, each dedicated to a specific function.Infineon-EVA-IHW65R62EDS06J-Evaluation-Board-fig-18
  • Note that for the 2ED21824S06J and the 2ED21844S06J, the minimum dead time is to be set by means of an external resistor. In this case, the software can force a dead-time value only if this is higher than the one set by the hardware. Please refer to the specific gate driver datasheet for further information ([3], [4]).
  • Once the BootKit XMC1300 is connected to the computer, the serial communication between the computer and the board can be performed as following (refer to Figure 13):
  1. Press “Get Port List” button
    • a. the available COMs are displayed in the drop-down menu
  2. Select the “JLink port”
  3. Press the “CONNECT” button and check that the bar turns green, and the text “Connected to Port xyz” appearsInfineon-EVA-IHW65R62EDS06J-Evaluation-Board-fig-19

The user interface provides an easy way to select the right gate driver IC model to configure properly the driving PWM signals generated by the MCU. The model of gate driver must be selected in accordance to the specific daughter card used. To select a gate driver model, the procedure is shown in Figure 14. Changing the gate driver model in the software is allowed only when the system is not running.
Attention: Selecting a gate driver model that does not match the model mounted on the board is likely to result in incorrect signal generation, and consequently in a high risk of IGBT failureInfineon-EVA-IHW65R62EDS06J-
Evaluation-Board-fig-20

The software also allows for an easy change of PWM signals parameters (e.g. frequency, duty cycle, dead time), as shown in Figure 15. The MCU, once programmed for the first time, contains default values that can be retrieved using the button “Read Data.” Any modification of the default parameters can be temporarily set in the MCU by using the button “Set Data.” The temporary setting is valid until the MCU is powered on. In case the MCU is turned off, the values of the parameters return to the default values. The user can always save new default values in the MCU flash memory by using the button “Write Data.Infineon-EVA-IHW65R62EDS06J-Evaluation-Board-
fig-21

Table 6 lists and describes the PWM parameters that can be configured. Note that some parameters are related to each other (e.g. switching frequency is the reciprocal of the switching period), so they cannot be changed independently.
Table 6 Explanation of PWM parameters

Parameter name Parameter description Parameter unit
FS Switching frequency of the PWM signal kHz
TS Period of the PWM signal – reciprocal of FS ns
TON,LS On-time duration of the PWS signal that drives the low-side IGBT –
related to TON,HS and to TS/FS ns
TON,HS On-time duration of the PWS signal that drives the high-side IGBT –
related to TON,LS and to TS/FS ns
dtLS,HS Dead time between low-side turn-off and high-side turn-on ns
dtHS,LS Dead time between high-side turn-off and low-side turn-on ns
  • At any time, the given parameter configuration of the GUI can also be saved in the computer and loaded later.
  • This may be particularly convenient if a given test configuration has to be reused multiple times. To save and load the configuration, refer to Figure 16. This figure also shows how to set the limits for the PWM parameters, which is particularly useful to prevent entering unwanted values accidentally.

  • Once the MCU has been properly set, the generation of the PWM signals can be enabled or disabled by pressing the START and STOP buttons.
  • Additionally, the user interfaces provide an additional control section that is used for:
  • Providing visual feedback on whether the PWM signals are being generated
  • Setting the PWM signals to be operated only for a limited number of pulses (e.g. to perform a start-up test of the system)
  • Enabling/disabling the MCU to output the signals (this option can be useful to verify the idle states of the IGBT driving signals)
