Abstract

See full text

A hybrid compensation system is electrically connected between a power grid and a load. The hybrid compensation system includes an active filter, a passive filter and a control unit. The active filter generates an output current. The active filter includes a switching circuit, a DC bus capacitor and a filtering inductor. The control unit includes a voltage controller, a first reactive current detector, a harmonic current compensator, a current loop controller and a modulator. The voltage controller generates a first current given signal according to a bus voltage of the DC bus capacitor and a reference voltage. The first reactive current detector generates a second current given signal. The harmonic current compensator generates a third current given signal. The current loop controller generates a control signal. The modulator generates a driving signal according to the control signal.
