LCL Resonant Soft-switching Single Stage single-phase Grid Connected Inverter
A novel soft switched grid connected single phase inverter topology is proposed and analyzed in this paper. Single phase single stage inverter consist of a full bridge converter (FBC) and a center taped rectifier interfaced with a high frequency transformer. To achieve Zero Voltage switching of the DC side Mosfets and reduced harmonics at the output side LCL-T resonant tank is introduced at the primary side of the high frequency transformer. Phase shift modulation of DC side full bridge is implemented for power flow control from DC to AC side. AC side converter is line frequency switched resulting in reduced switching losses. The performance of the proposed inverter topology is analyzed under different operating conditions for 200W prototype. Detailed analysis of converter and effect of secondary leakage inductance on the overall performance of the converter has also been analyzed.
