Resonant Pulse Power Converter with a Self-Switching Technique

Abstract

In this paper a resonant pulse power converter (RPPC) is proposed The proposed RPPC transfers the pulse shape power from a DC source to a load periodically The RPPC consists of a resonant circuit and a resonant pulse converter driven by a self-switching circuit Depending on the magnitude difference between the input and output voltages the operations of the RPPC are divided into 4 modes, boost mode hybrid mode direct mode and cut-off mode respectively The main switch of the RPPC turns on in the ZCS condition and off in the ZVS condition spontaneously The operational principles of a RPPC using the self-switching technique are analyzed and verified in experiments An example of a RPPC application is demonstrated in the area of thermoelectric energy harvesting
