Abstract

In the electrolytic capacitorless inverter system, resonance occurs between the inductance on the grid side and the DC-link capacitor. Because of this resonance, the regulation of the input current harmonic may not be satisfied in some cases. In order to satisfy harmonic regulation, a method for controlling this input current by direct DC-link current control has been proposed using PWM modulation. In PWM modulation, the switching frequency depends on the carrier frequency. This paper proposes a control method that reduces the switching frequency and satisfies the harmonic regulation via model predictive direct current control (MPDCC). This paper is confirmed that the proposed method reduces harmonics of input current and switching frequency. The effectiveness of the proposed method is verified by numerical simulation.
