Abstract :
A series resonant DC link converter with PWM capability and current peak limiting is proposed. When desired, resonant transition creates notches in the DC link current, allowing the switches of the converter to synchronize with external PWM strategy. For that, it requires only an additional bi-directional switch. A saturable core achieves current peak limiting. The clamping level is automatically adjusted by the current load
