Analysis of leakage current suppression mechanism of Heric change topology and double parallel Buck inverter topology

1. Heric change topology 1 Figure 1 shows a non-isolated topology based on the Heric structure. This topology moves a freewheeling switch in the Heric topology to a group of bridge arms. Using the unipolar SPWM strategy shown in Figure 2, in the power transmission stage, current flows through S3-S2 (positive direction) and S1-S5-S4 (negative direction); In […]
