HYAPF series cabinet active filter
Fundamental
The active power filter is connected to the power grid in parallel, and the voltage and current of the compensation object are detected in real time, calculated by the command current operation unit, and the lower module of the IGB is driven by wide-band pulse modulation signal conversion technology. Input the current with opposite phase and equal magnitude to the harmonic current of the grid to the grid, and the two harmonic currents just cancel each other out, so as to achieve the functions of filtering harmonics and dynamically compensating for reactive power, and obtaining the desired power supply current.

HYSVG Static Var Generator
Fundamental
The basic principle of STATCOM, a static var generator (also known as SVG), is to connect the self-commutated bridge circuit directly in parallel with the power grid through the reactor, and properly adjust the phase and amplitude of the output voltage of the AC side of the bridge circuit or directly control Its AC side current can make the circuit send out reactive current that meets the requirements, and realize the purpose of dynamic reactive power compensation.
Three working modes of SVG -
