Manufacturers and users of UPS power supply system have long noticed the matching problem between generators and UPS, especially the harmful effects of current harmonics generated by rectifiers on power supply systems such as voltage regulators of generators and synchronous circuits of UPS. Therefore, the technicians designed the input filter and applied it to UPS, and successfully controlled the current harmonics in UPS application. These filters play a key role in UPS compatibility with generators.

In fact, all input filters use capacitors and inductors to absorb the destructive current harmonics at the UPS input. The design of the input filter takes into account the percentage of all possible harmonic distortion inherent in the UPS circuit and at full load. Another benefit of most filters is to increase the input power factor of UPS with load. However, another consequence of the application of input filters is to reduce the overall efficiency of UPS. Most filters consume about 1% UPS power. The design of input filters has been seeking a balance between advantages and disadvantages.

In order to improve the efficiency of UPS system as much as possible, UPS engineers have recently improved the power consumption of input filters. The improvement of filter efficiency depends largely on the application of IGBT (Insulated Gate Transistor) technology to UPS design. The high efficiency of IGBT inverters leads to the redesign of UPS. The input filter can absorb some current harmonics and a small part of active power. In short, the ratio of inductance factor to capacitance factor in the filter is reduced, and the volume of UPS is reduced and the efficiency is improved. The compatibility between UPS and generators is another problem.

With the development of economy and society, the power quality of the power industry and the reliability and safety requirements of power supply are getting higher and higher.
How to compensate the power quality of the power grid (including harmonics, reactive power and unbalance) has become the focus of power grid research. In addition to continuous innovation in management, it is more urgent to adopt and promote some good technical measures to more effectively improve the reliability and safety of power supply.
SOROTEC is dedicated to solving the problem of power quality for users. The series of APF / SVG / SPC adopts modular design, which can run in parallel at the same time. The loss of the whole machine is less than 3%. It is fully suitable for various situations in industrial and civil fields, and is the best solution for power quality management.

The following is a brief introduction to the advantages of this series of products.

1.Higher compensation accuracy and stability

1)With using he quasi-4-core 28377CPU, the computing power is more than 5 times higher than 28335CPU. The 16-bit A/D sampling is adopted to support the calculation and compensation of higher harmonics. The control bandwidth is more higher than before. The switching frequency ups to 20kHz with higher control accuracy and stability.
2)When double precision sampling technology is adopted, the control frequency ups to 40kHz. It not only improves the calculation accuracy but also further improves the phase margin of the control system, thus ensuring the compensation accuracy and stability of the system.
3)The voltage sharing control technology of positive and negative dc bus is adopted to ensure the control precision of output current.。

2.Higher security

1)Providing more comprehensive protection scheme: not only support the traditional short circuit protection, but also support over-voltage protection, over-current protection, under-voltage protection of the driving power supply, truly achieve the IGBT fault prevention and protection, so as to ensure the safe operation of the device;(The protection threshold of conventional IGBT short-circuit protection is 3 to 5 times of the IGBT peak current, which is mainly used to prevent secondary accidents caused by the damage of IGBT. But it cannot prevent the damage of IGBT caused by the over current. The protection threshold of our company’s over current protection is 0.8 times of the IGBT peak current, which can effectively protect the safe use of IGBT.)
2)The carrier synchronization technology is adopted to ensure that the switching frequency of the parallel module is completely consistent, which can effectively avoid high-frequency circulation；

3.Higher reliability

1)The dynamic peak current limiting algorithm is adopted to ensure the maximum power output of the device’s compensation capacity and prevent overcurrent protection in the case of any wave peak ratio. So the operation reliability is higher.；
2)The real-time monitoring of electrolytic capacitor life of dc bus is supported. The working mode is adjusted according to the monitoring results to ensure the stable operation of the device and extend the service life of the electrolytic capacitor.。

4. More convenient management mode

It not only supports the random independent management and configuration mode of WIFI wireless communication, but also supports the remote unified management and configuration mode of GPRS wireless or wired communication

5.Lower power consumption

Thanks to the profound understanding of power electronics high-speed switching devices, the active power loss of 100kVA device is less than 2.5% when the device is fully loaded.

6.Other deep optimization

1)The filter capacitor with the voltage grade of 320V is adopted to ensure that the capacitor is not damaged under the responsible working condition with higher safety.
2)The relay delay shut-off design is adopted. When the device is out of operation, the relay does not shut off IGBT at the same time, so as to extend the life of the relay；
3)When the multi-module cabinet is running, if one module is out of fault, other modules can adaptively compensate the vacancy capacity . So the compensation is more stable and reliable.；
4)In the case of inductive load, the device adopts the operation mode of control power factor. In the case of capacitive load, the device can fully compensate capacitive reactive power under the premise of adequate compensation capacity. The power factor can be increased to 1 at maximum.；
5)The device supports the reactive loss of synchronous compensation transformer；
6)Supporting phase judge function, it can automatically identify phase connect wrong, connect reverse situation, and alarm prompt.
