In this paper, we proposed a form of load resonant inverter made which use of soft switching technology to reduce stress and turn on/off loss at switching and described about its principle operation with coupling coefficient. The general operation characteristic of the inverter is depicted by introducing normalized control variables. The characteristic of the inverter are evaluated by load time constant and a coupling coefficient. When the load changes suddenly from steady state operation, the characteristics are analyzed. Based on the characteristics value, a method of circuit design is proposed. In addition, the results of its characteristics analysis are compared with that of pspice's simulation and experimental waveform are compared with theoretical ones.
