Design and Placement of a Passive Clamp Snubber for Isolated SEPIC and Cuk Converters Working as Automatic Power Factor Correctors

IEEE Open Journal of Power Electronics
DC-DC power converters with galvanic isolation and using only one power transistor need elements that limit the voltage spikes at the beginning of the transistor turn-off. These elements are called clamp snubbers.
