Abstract :
This paper describes a novel way to implement soft switching in DC/DC converters for high current low voltage applications in the automotive field. Adding resonant elements to a bidirectional buck boost converter enables resonant behaviour. In simulation and laboratory it will be shown that this behaviour reduces the switch-off losses strongly.
