Abstract :
A closed-loop mc × nc -stage switched-capacitor-voltage-multiplier boost inverter (SCVMI) is proposed by combining phase generator and sinusoidal-pulse-width-modulation (SPWM) control for low-power boost DC-AC conversion/regulation. The power unit contains: SCVM booster (front) and H-bridge (rear). This booster consists of two mc -stage SC cells and two nc -stage SC cells in series, and these cells are operated with two-phase interleaved non-overlapping clocks of phase generator for a conversion ratio of mc × nc at most. The H-bridge consists of 4 switches, and these are controlled by SPWM to realize full-wave DC-AC operation and output regulation. Further, the modelling and analysis of SCVMI are included. Finally, the closed-loop SCVMI is simulated, implemented, and tested. All the results are illustrated to show the efficacy of the proposed scheme.
