The single-phase PWM rectifier has a second harmonic current and a corresponding ripple voltage on the DC side. The low-frequency harmonic current is usually eliminated by a resonant circuit composed of a large-capacity capacitor and an inductor in the DC bus, but the LC brand reduces the power density of the entire system. To this end, a secondary pulsation active power filter based on a bidirectional boost–buck converter (bidirectional buck/boost) is proposed to suppress the DC bus voltage secondary pulsation. The compensation current equation when the filter fully compensates the pulsating power is derived, and a voltage loop and current loop control strategy is proposed based on this. Based on MATLAB/Simulink simulations and experiments demonstrate the effectiveness of the scheme, it can also reduce the volume and improve the power density of the system.
