Abstract :
In this paper, a new type of PWM series resonant converter is proposed. One pole of the proposed converter is switching at zero-current and the other is switching at zero-voltage. By introducing an auxiliary inductor, zero-voltage switching is possible even at no load. The proposed converter is suitable for a high-voltage DC/DC converter because the voltage stresses of switching devices are minimized
