Verify output ripple and noise

• Test overview:

• Ripple: The ripple is the AC component superimposed on the output of DC voltage; The ripple voltage is the peak-to-peak value between the peaks and valleys of the fingerprint wave; during each on-and off process, the electric energy is extracted from the input terminal to the output terminal to form a process of charging and discharging, thereby causing fluctuations in the output voltage.
  noise:

• Noise voltage refers to its peak-to-peak value, in switching power supplies, there are two main reasons for formation:

• (a) A high-frequency pulse train generated by the switching power supply itself, which is caused by a sharp pulse generated when the switch is turned on and off.

• (b) Interference from external electromagnetic fields, entering the switching power supply through radiation or entering the switching power supply through the power line;

• In the switching power supply, the noise is mainly related to the switching process of the system.

• Preset conditions: room temperature

• Test instrument: oscilloscope, common probe (with 1:10 probe), electronic load Test environment: 220V power supply, SPS5081X set output to 24V/15A ,full load output, electronic load set to 14.96A.

Test methods and steps:

• (a). The probe is grounded in the shortest grounding manner. It is recommended to use a grounding spring well connected to the SPS5081X sense terminal.
• (b). The oscilloscope turns on the bandwidth limit of 20MHz, set the appropriate time base and storage depth to ensure the sampling rate is 100M/s, set the probe amplification factor to 1:1, the coupling mode is AC coupling, turn on the statistical function, and record the valid value, peak-to-peak value, maximum value, and minimum value, then save them as screenshots.
• Other instructions: In order to get more accurate results, grounding should be tested with reference to the following methods.

Verify the output voltage overshoot of on/off

Test overview:

Output overshoot: The output voltage of the power supply will generate voltage overshoot at the moment of switching. This is mainly related to loop feedback stability. The linear power supply is used as a laboratory power supply equipment, so it should not have overshoot strictly.

• Test instrument: oscilloscope, ordinary probe
• Specifications: no overshoot
• Preset conditions: room temperature
• Test environment: 220V power supply, the probe is grounded in the shortest way.

Test methods and steps:

• (a). Set the oscilloscope in single trigger, select the appropriate trigger level, and use the oscilloscope’s measurement function.
• (b) When the power input is turned on or off, test the voltage waveform of the output of the power supply under no-loading and full-loading conditions.

Verify transient response recovery time

Test overview:

• The transient response of the regulated power supply can be divided into source transient response and load transient response, and the recovery time is generally used to predict the quality of the transient response. The transient voltage characteristic is an inherent characteristic of the power supply itself. There are many energy storage components inside the power supply. The voltage adjustment needs to read back from the output, compare the standard voltage, and adjust the switching duty cycle.
• Increasing the speed of the control loop provides shorter transient response times. However, it is possible that the output is very unstable and even oscillates. If the voltage transient response capability is poor, the voltage drop/overshoot time is too long and the amplitude is too large, which directly causes many problems. This will make the measurement not work properly. Therefore, if you have such an application, you must consider a power supply that is more responsive.
• Specifications: When the output current is from half load to full load, the output voltage is restored to within 0.1%Vset+10mV for less than 1ms.
• Test instrument: oscilloscope, common probe, electronic load
• Preset conditions: room temperature
• Test environment: 220V power supply, the probe is grounded in the shortest way.

Test methods and steps:

• (a). Turn on the power of the instrument, set the oscilloscope to AC coupling, DC trigger mode, select the appropriate trigger level, and the probe test point is the positive and negative terminals of the output of the power supply;
• (b). The SPS5081X power supply connect to the electronic load, and the electronic load set to the dynamic test mode. The relevant settings are as follows: set to continuous mode, set the rising and falling slopes to10A/us, set level A=4.5A, level B=2.25A, set the frequency to 10Hz, set the SPS5081X to 80V/5A, and the screenshot retains the test result;

Calibration channel parameters

Calibration instructions:

• The parameters to be calibrated are the voltage setting value, voltage displaying value, current setting value and current displaying value. All parameters are determined by linear calibration and the fitting function is Y=aX + b. “a” is the linear coefficient and “b” is the offset. In order to determine the parameters “a” and “b”, it is necessary to know two corresponding points, namely (x1, y1), (x2, y2) and then find their parameters “a” and “b”. The system can implement calibration commands through a combination of SCPI commands. Send SCPI commands through the NI interface.
• Users can control the instrument remotely by using National Instruments Corporation’s NI-VISA. NI MAX is a user interface that controls the device.

Open the NI Control Command interface

Step:

1. Open the NI MAX user port interface;
2. Click on the “device and interface” in the upper left corner, find the connected power supply information, click on the power supply device and click “Open VISA Test Panel”, then pop up the bullet box. As shown in Figure 3-1 below.

Hardware troubleshooting

This chapter describes how to handle common hardware failures encountered during power operation. Before handling such fault, ensure that the power supply meets the following prerequisites.

1. If one voltage value is found to be different from the nominal value when measuring voltage, turn off the power immediately.
2. Turn off the power before unpacking the connecting wire of the mainboard and the screen backlight.
3. During the process of taking apart the instrument for measurement, take measures to prevent static electricity from damaging the internal components.

ESD Precautions

• While performing any internal test of the power supply, please refer to the following precautions to avoid damages to its internal modules or components result from ESD.
• Touch circuit boards by the edges as possible as you can.
• Reduce handling of static-sensitive modules when necessary.
• Wear a grounded antistatic wrist strap to insulate the static voltage from your body while touching these modules.
• Operate static-sensitive modules only at static-free areas. Avoid handling modules in areas that allow anything capable of generating or holding a static charge.

Required Equipment

• The equipment listed in the table are required to troubleshoot the power supply.

Table 5-1required equipment

MainBoard Drawing

Main board is used to control and manage the whole internal system of the power. Please refer to the following drawing to quickly locate the test points on the main board for easy resolution of the failures you encounter.

Troubleshooting flowchart
The following is a flow chart of the power hardware failure. The following figure can help you quickly locate and handle related hardware failures .

Check the power supply

Make sure that the power supply is properly grounded through the protective grounding end of the power cord. Be careful not to touch or disassemble the main board to avoid electric shock or burns. Please check the power supply as follows:

In Figure 5-4 there are 4 capacitors marked with red rectangle. The power supply voltage can be measured between two terminals of these 4 capacitors, CD57, CB10, CD56, CD69. Voltage parameters are showed in Table 5-2.

In Figure 5-5 there are 2 capacitors marked with red rectangle. The power supply voltage can be measured between two terminals of these 2 capacitors, C2, C5. Voltage parameters are showed in Table 5-2.

Table 5-2: Power supply voltage parameter table

CAUTION: DIFFERENT GROUND CAN NOT BE CONNECTED

• If the measured voltage value is consistent with the corresponding parameter in the table, use the oscilloscope to check the waveform of the voltage. If the waveform is flat, the power supply works well.
• If the measured voltage value does not match the corresponding parameter in the table, proceed to the next step. Besides, if the power supply voltages are all 0V, the fuse on the bottom board also should be checked (need disassembling).
• Turn off the SPS5000X and wait for several minutes, then measure the resistance between the capacitors mentioned above, to exclude circuit-short on main board. If there is no circuit-short, you need to replace a new AUX board.
• To ensure safety, do not disassemble the main board and the isolation slice on the side unauthorizedly.
