摘要
A circuit for clamping a voltage across a switching element to a value equal to or less than the sum of the input voltage plus the voltage across a clamping capacitor is provided. The circuit achieves voltage clamping in a circuit configuration in which an active clamp circuit includes a switch and a clamping capacitor connected in parallel with a first winding of a coupled winding. The active clamp prevents the occurrence of voltage spikes across a first switching element. The clamping capacitor serves a second function in that it recovers energy stored in the first winding of the coupled winding.
