Abstract: Along with the government and market take more and more attention to the energy efficiency of power supply, the loss of IGBT module, as the core device, has become a hot topic. Firstly, the dynamic process of IGBT module is analyzed, an accurate and an estimation method of loss calculate are provided, then the working process and resonant process of phase shift full-bridge soft switching converter is discussed, and constitute of IGBT module loss in the circuit is analyzed. Finally the loss is calculated in the 350A inverter welder example, and a conclusion of reliability and proposal for design are given according to the calculation results.
