A novel regenerative snubber circuit for flyback topology converters [PDF]
Journal of Vibroengineering, 2020 Switch mode power suppliers based on isolated flyback topology have voltage stresses on semiconductor switches caused by transformer leakage inductance. Those voltage stresses have to be mitigated by implementing active or passive clamp preferably with partial leakage energy recovery.
