In this paper, a novel type of auxiliary switched capacitor assisted edge resonant soft switching PWM resonant DC-DC converter with two auxiliary edge resonant lossless inductor snubbers. The operation principle of this converter is described using the switching mode equivalent circuits. This newly developed multi resonant DC-DC converter can regulate its dc output AC power under a principle of constant frequency edge-resonant soft switching commutation by asymmetrical PWM control scheme. The high frequency power regulation and actual power conversion efficiency characteristics of the proposed soft switching PWM series load resonant DC-DC converter are evaluated. The operating performances of the newly proposed soft switching inverter are discussed based on simulation results from an application point of view
