Analysis of leakage current suppression mechanism of H5, Heric and H6 topology

1. H5 topology Figure 1 is SMA SoLdr’s patented topology-H5 topology [8], this topology has a switch S5 in series in the main loop of the full bridge circuit. The H5 topology uses unipolar SPWM modulation, and its driving logic diagram is shown in Figure 2. In the power transmission phase, current flows through S5-S1-S4 (positive direction) and […]
