Analysis of leakage current suppression mechanism of H5 changing topology
1. H5 change topology 1 Figure 1 is a circuit structure of a six-switch non-isolated inverter, using the unipolar SPWM strategy shown in Figure 2. This topology adds a switch tube based on the H5 topology. In the power transmission phase, current flows through S5-S1-S4 (positive direction) and S6-S2 (negative direction); in the freewheeling phase, the current flows […]
