Abstract :
Multi-resonant and quasi-resonant power converters have been modified to provide constant-frequency operation. Power transformer leakage inductance has been used to adapt the traditional PWM control to these power converters. Conventional PWM integrated circuits can be used for the power converter regulation. Several experimental results are developed to test the control method proposed
