Product Usage Instructions

Introduction to DC Bus Systems
DC bus systems can be categorized as regenerative and nonregenerative. Regenerative systems can generate power back to the mains network, suitable for high braking power needs. Nonregenerative systems redistribute braking power to other drives via the common DC bus.

Benefits of Common DC Bus Systems
Common DC bus systems offer cost savings, reduced power cabling, installation time, and overall footprint. They improve tolerance to voltage dips/sags and minimize harmonic distortions in the drive system.

In Harmony with the Environment
The Common DC bus portfolio meets international standards for safety, EMC, and harmonics approvals. Innovative solutions focus on energy efficiency and smart grid technology.

Modular drive solutions

We offer a comprehensive range of Common DC bus drive products comprising front-end units, inverter units and brake chopper units in the entire power range and voltages from 380 V to 690 V. The drive components are built on proven VACON® NX technology and provide the ideal energy sharing solution for a multitude of power systems.

Reliable. Robust. Proven.
When your goal is to ensure that all AC drives share energy within your industrial system, and that all energy is effectively utilized and redistributed, then VACON® Common DC bus drive solutions are the right choice. Our Common DC bus components are used in a multitude of combinations across a wide spectrum of high-power process industries from the pulp and paper, steel, metal and mining and marine cranes to smaller machines and production lines, which also demand cost-effective solutions.

DC bus systems comprise two main categories: regenerative and non- regenerative. In a regenerative DC bus system the front-end unit is capable of generating power back to the mains network. This kind of system is suitable for processes where braking is needed often and the braking power is relatively high. In a non-regenerative system the braking power  is redistributed to the other drives in the system via the common DC bus, and possible excess power can be dissipated as heat using an optional brake chopper unit and brake resistors. In small production lines or small paper machines where braking is needed less often, a non-regenerative common DC bus system is a cost-efficient solution. In high power applications, it is possible to parallel multiple front-end units.

In addition to the welcome cost savings, you’ll also benefit from reduced power cabling and installation time and reduced overall footprint of your drive system. Your drive line-up tolerance
to voltage dips/sags will be improved and the harmonic distortions your drive system will be minimized.

In harmony with the environment
We are an environmentally responsible company and our energy saving products and solutions are a good example of that. Our Common DC
bus portfolio fulfills key international standards and global requirements, including safety and EMC and Harmonics approvals. Likewise, we continue to develop innovative solutions utilizing for example regenerative energy and smart grid technology to help customers effectively monitor and control energy use and costs.

The complete range

VACON® Common DC Bus product portfolio meets all the requirements with a flexible architecture, comprising a selection of active front-ends, non- regenerative front ends, inverters and brake choppers in the entire power range and voltages from 380 V to 690 V.

Flexible configuration, customized solutions
Common DC bus components can be used in a multitude of combinations. In a typical DC bus configuration, the drives that are generating can transfer the energy directly to the drives in motoring mode. Common DC bus drive systems have different kinds of front-end units to meet the requirements of the electricity network and the process where the drives are used.
With the right configuration, the drive system can achieve optimal performance and significant energy savings can be made when braking energy is utilized to its full potential.

Front-end units
The front-end units convert a mains AC voltage and current into a DC voltage and current. The power is transferred from the mains to a common DC bus and, in certain cases, vice versa.

Active front-end (AFE)
The AFE unit is a bidirectional
(regenerative) power converter for the front-end of a common DC bus drive line-up. An external LCL filter is used at the input. This unit is suitable in applications where low mains harmonics are required. AFE is able to boost DC link voltage (default +10%) higher than nominal DC link voltage (1,35x UN). AFE needs an external pre-charging circuit. However, AFE does not need any external
grid side measurements to operate. AFE units can operate in parallel to provide increased power and/or redundancy without any drive to drive communication between the units. AFE units can also be connected to the same fieldbus with inverters, and controlled and monitored via fieldbus.

Consistently reliable
Our proven performance, reliability and drive system modularity meet the needs of pulp and paper drive systems around the world.

Typical device configurations

Non-regenerative front-end (NFE)
The NFE unit is an unidirectional
(motoring) power converter for the front-end of a common DC bus drive line-up. The NFE is a device that operates as a diode bridge using diode/thyristor components. A dedicated external choke is used at the input. The NFE unit has the capacity to charge a common DC bus, thus no external pre-charging is needed. This unit is suitable as a rectifying device when a normal level of harmonics is accepted and no regeneration to the mains is required. NFE units can be paralleled to increase power without any drive to drive communincation between the units.

Inverter unit (INU)
The INU is a bidirectional DC-fed power inverter for the supply and control of AC motors. The INU is supplied from a common DC bus drive line-up. A charging circuit is needed in case the connection possibility to a live DC bus is required. The DC side charging circuit is integrated for powers up to 75 kW (FR4-FR8)  and externally located for higher power ratings (FI9-FI14).

Brake chopper unit (BCU)
The BCU is a unidirectional power converter for the supply of excessive energy from a common DC bus drive line-up to resistors where the energy is dissipated as heat. External resistors are needed. By using two brake resistors, the braking power of the brake chopper is doubled.

Multiple options

VACON® NXP Control
VACON® NXP offers a high-performance control platform for all demanding drive applications. The microcontroller provides both exceptional processing power and small footprint. The VACON® NXP supports both induction and permanent magnet motors in open and closed loop control modes. It also provides bumpless control for transferring between open loop and closed loop.

• In which potentially explosive gas, vapor, mist or air mixtures are present
• With combustible dust.

If over-heating is detected, the drive immediately stops feeding energy to the motor. As no external components are needed, the cabling is minimized, improving reliability and saving on both space and costs.

DC cooling fans
VACON® NXP high-performance air-cooled products are equipped with DC fans. This significantly increases the reliability and lifetime of the fan also fulfilling the ERP2015 directive on decreasing fan losses. Likewise, the DC-DC supply board component ratings fulfill industrial requirement levels.

Conformal coating
To increase performance and durability, conformally coated circuit boards (also known as varnished boards) are provided as standard for power modules (FR7 – FR14).
The upgraded boards offer reliable protection against dust and moisture and extend the lifetime of the drive and critical components.
