Introduction to Modular Power Quality Regulators
Our modular power quality products include: Static Var Generators (SVGs), Advanced SVGs (ASVGs) and Active
Power Filters (APFs). They have features such as high power
density, enhanced reliability, optimized performance, high
utilization and unique designs. For use in different application
scenarios, there are three way to install them: drawer style,
wall-mounted style and upright style.

Main Features of Modular Power Quality Regulators
Our modular power quality regulators:
- Are compact, with a maximum size of only 0.05m³, have a high power density, and apply to a variety of scenarios. In practice, they are more applicable to places where limited space poses a stringent requirement on the ground they could cover, as well as power distribution upgrading projects.
- Employ the same design concepts as industry-grade products, and therefore, highly adaptable to the environment.
- Furnish the module control layer with a board compartment that reaches a dust-proof rating of IP6X and has withstood the nationally recognized third-party lab testing.
- Apply an interleaving control manner at the output end. This reduces at least 40% of global ripple current.
- Support a dynamic response at ms level, with a global response time less than 2ms. Therefore, they can accurately track how transient current changes in the power grid and prevent over-compensation and under-compensation.
- Employ an industry-leading redundant design based on Insulated Gate Bipolar Transistors (IGBTs). As a result, failure in one line will not affect the proper running of the system.
- Allow devices to detach from the power grid in case of a breakdown, with no port capacitors remain connected to the grid, thus preventing any negative impact on the harmonic oscillator and capacitive reactive power of the grid.
- Support a CT connecting at the power supply side or the load side, which you can adjust according to on-site requirements.
- Have a fast and thorough fault self-diagnosis function, which can be intelligently adjusted based on actual operating conditions and states.
- Make it easier to maintain by using separately removable parts such as bus capacitor and fan.
- Support a smart algorithm, which automatically adjusts the compensation proportion based on real-time changes in reactive current and harmonic current, and also supports flexibly setting a compensation goal, in order to optimize your business objective.
- Support smart sleep in which two parallel systems apply a polling mechanism to allocate an average worktime for each module under a light load condition, thus extending module lifetime.
- Have passed the CE certification and conform to EN 62477-1: 2012+A11-2014+A1-2017 standard;
- An APF supports a wider range of compensation, that is, instantaneous 2nd - 51st harmonic compensation;
- An ASVG supports 2nd - 23rd harmonic compensation. You can set harmonic compensation capacity and reactive compensation capacity globally.
- An SVG supports global, instantaneous compensation for inductive reactive power and capacitive reactive power, and meanwhile, solves the three phase unbalance problem.
Enhanced Reliability & Performance
Industry-first dust-proof module at the control layer: The control section is separated from the power section. The control layer applies a fully closed dust-proof design, with no vent holes at two sides, front and back, thus obtaining an excellent sealing; while at the air cooling layer, critical power units are cooled by the power layer, thus achieving a superior device cooling performance. In addition, the control layer reaches a protection class of IP6X and has withstood the third-party lab testing. This isolates the control section from being polluted by the outer world. Besides, we employ an industry-grade hardware design, which further improves security and reliability.
At the dust-proof certification test After the dust-proof
certification test
In the response test of a sudden load rise, the oscillometer record shows that the global response time on the display is 1.36ms.
In the response test of a sudden load drop, the oscillometer record shows that the global response time on the display is 1.96ms.

Use of a separate control scheme for each IGBT, which is much more
reliable because: each IGBT is equipped with a set of drives and a
hall element, and in the case that the IGBT on one side fails, the
device still could offer 50% of the rated output capacity.
Providing a soft-start relay and resistor between a filter capacitor and the power grid, to ensure that when a device fails, the filter capacitor breaks away from the grid, without posing any secondary impact on the grid.

- Quicker response: Use of a Second-Order Generalized Integration (SOGI) algorithm achieves a global response time of less than 2ms, making it possible to accurately tract how harmonic content and reactive content change in the power grid and prevent over-compensation and under-compensation.
In the response test of a sudden load rise, the oscillometer record shows that the global response time on the display is 1.36ms.
In the response test of a sudden load drop, the oscillometer record shows that the global response time on the display is 1.96ms.
- Advanced harmonic suppression technology: Quickly suppresses the harmonic state in less than 1s after a device detects that harmonic current is inevitable in the power grid, making sure that the device will not be turned off entirely so that it can go on performing compensation for the system.
- Low ripple output: An interleaving-based low-ripple control technology achieves a smooth waveform even for a 60th harmonic output.
