    Overview 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 harmo...

    HYSPC three-phase load...

    Overview Three-phase imbalances are common in low voltage distribution networks. Due to the existence of a large number of singlephase loads in urban and rural networks, the current imbalance between the three phases is particularly serious. The current imbalance in the power grid will increase the loss of the line and transformer, reduce the output of the transformer, affect the operation safety of the transformer, and cause zero drift, resulting in three-phase voltage imbalance, and reduce ...
