Abstract :
A novel bi-directional series resonant inverter is present in this paper, which all switch can work in a ZCS condition with fixed frequency. A bilateral switch is connected to primary side of transformer which will control the energy following more perfectly. With the bi-directional switch k degree of current control was improved. Power flow with different switch combination was analyzed and its waveform library was used to control the energy following. The topology has a bright prospect in low THD inverter and special inverter. Experimental result proves the validity of the theoretical analysis
