Abstract :
Asymmetrical half-bridge converters with single output diode are known for ZVS, fixed frequency, PWM operation and good transformer utilisation. However, ZVS is obtained only at proper converter design. This paper provides uniquely a transition modelling and reveals that ZVS conditions can definitely not be calculated by simply regarding the energy in the inductors
