三相单级矩阵式隔离型AC-DC变换器及其三阶谐振槽控制策略

This article proposes a control strategy for the three-phase single-stage matrix-type LCL resonant ac–dc converter. A five-level voltage is generated through the matrix converter, and the derivation process is simplified using the fundamental harmonic analysis method. The critical soft-switching conditions are modified to achieve fully zero-voltage switching for all switches. Analytical expression...
