External CT detects the load current, DSP tracks instruction current, and calculates the reactive power change rate through the instantaneous Reactive Power Algorithm. Then DSP sends a PWM signal to the IGBT driving board which can control the IGBT on and off to generate inductive or capacitive compensation current. At the same time, CT detects the output current and the compensation result is fed back to DSP, then the next round of logic control is carried out to realize a stable power grid.
