[QUOTE="Baluncore, post: 6494904, member: 447632"] If a switch such as a diode turns on or off through it's inherent characteristics and position in the circuit, then it is "soft commutation". If it switches because it is controlled by an external signal then it is "hard commutation". The anti-parallel diode, or the body diode across a mosfet is inherent = soft commutation, the mosfet is controlled = hard commutation. If you replace the diode with a controlled synchronous rectifier, then it becomes hard commutation for both the on and off transitions. Y. Chéron (auth.), C. Goodman (eds.) - Soft Commutation - Springer Netherlands (1992) [/QUOTE]
