-APF active power compensator detects the load current in real time through the external current transformer, it calculates, abstracts and decomposes the reactive current component through DSP and drives the internal IGBT through the PWM signal so as to make the current transformer to produce a compensating current with the equivalent size and opposite frequency to the load harmonic current and inject it into the system so as to realize the dynamic filtering.
Performance characteristics:
Quick response: capture time＜100μs, complete compensation time＜10ms;
Significant Effect：THDi＜5%;
Flexible: modular design, convenient for the third party to embed;
Component concept: easy to be transported, used and maintained.
