Abstract
An RCD clamp circuit is usually used in flyback converters, in order to limit the voltage spikes caused by leakage transformer inductance. Oscillation ringing appears due to the clamp diode, which deteriorates the converter´s power rate. This brief describes this ringing phenomenon and the use of an RC-RCD clamp circuit for damping the clamp diode´s oscillation. This clamp circuit is capable for improving a flyback converter´s power ratio.
