A waveform control strategy for single-phase high-frequency link matrix inverter

A De-Re-coupling uni-polarity phase-shifted control strategy is proposed in this paper. This waveform control method can achieve zero voltage switching (ZVS) of all the switches in the matrix/cycloconverter and natural commutation of the filter inductance without auxiliary circuits and commutation overlap of the matrix/cycloconverter. For the uni-polarity phase-shifted controlled single-phase high-frequency link matrix inverter (SPHFLMI), a novel optimized waveform method is introduced to solve the problem of low voltage utilization and high harmonic components caused by dead-time through changing the setup of adding dead-time in this paper. The feasibility and effectiveness of the proposed strategy are verified by simulation and experimental results.
