Simulation Study of Single-Cycle Inner Loop Control to Single Phase High-Frequency Link Matrix Converter

Application of single-cycle control of the inverter can enhance the inverter DC input immunity. Controlling auxiliary voltage and current outer loop in a single cycle, the load capacity of a single-cycle control can be improved. In this paper, for single-phase voltage-type high frequency link matrix inverter, we study a new multi-loop SPWM control strategy based on single-cycle inner control. Simulation results show its effectiveness in restraining the DC side disturbance and carrying load capacity.
