Abstract :
This paper presents about characteristic estimation of of ZVS high frequency resonant inverter. The soft switching technique known as ZVS is used to reduce turn off loss at switching instants. According to the variation in capacitance of the DC voltage source separation capacitor the analysis of inverter circuit is generally described by using normalized parameter, normalized resistance and parameters. Also, this paper proves the validity of theoretical analysis through the experiment. This proposed inverter shows that it can be practically used as the power source system for the lighting equipment of a discharge lamp, DC-DC converter etc
