Audited Supplier
HYAPF / HYSVG detects the load current in realtime through the external current transformer (CT), calculates the harmonic/reactive component of the load current through the internal DSP, and sends it to the internal IGBT through the PWM signal, then generate a compensating current with the same amplitude but opposite phase angles to the detected harmonics / reactive power to achieve the filtering/compensation function.
Harmonic compensation: APF can filter 2 ~ 50 times random harmonics at the same time
Reactive power compensation: Capacitive & Inductive (-1 ~ 1) stepless compensation
Fast response
Design life is more than 100,000 hours (more than ten years)
