Design of a nondissipative turn-off snubber in a forward converter
The design of a nondissipative turn-off lC snubber for a forward converter is described. The operation of a forward converter with an LC snubber is first examined. The energy loss in the switching transistor is then evaluated, and the condition that minimizes this energy loss is determined. The optimum size of the snubber capacitor is derived from the evaluation of transistor energy loss and surge voltage. The optimum size of the snubber inductor is also obtained.<>
