Analysis and Simulation of LCL Resonant Inverter for Low Cold Resistance Application

In This paper, the steady state analysis of a 3rd order LCL resonant inverter is presented. The analysis of mathematical model shows that this topology has the capability of inherent over current protection. In addition, the inverter switches current stay in nominal value. This is suitable for low cold resistance which needs to limit the current at start-up condition. The simulation results verify the accuracy and validity of model and its performance in the mentioned usage
