Abstract :
The authors present the exact analysis of the full-bridge zero voltage switching (ZVS) pulse width modulated (PWM) converter by using the state-plane technique. Based on the analysis, they derive the necessary conditions for ZVS operation and the performance characteristics of the converter in terms of characteristic curves from which the converter design procedure can be formulated. The performances of the converter operating outside the limits of ZVS operation, including the switching loss and the attainable efficiency under different load conditions, are also given. The analytical work is confirmed by experimental results
