Reactive snubber for inductive load clamp diodes |
摘要 |
A saturable reactor snubber to improve the recovery characteristics of a clamp diode used in a power switching circuit is provided with a secondary winding to permit saturating the reactor via a secondary current pulse in order to improve the turn-on speed of the clamp diode. The current pulse for saturating the reactor at turn-on is preferably derived from a shunt snubber charging pulse or from an external generator synchronized to the turn-off time of a power switching device in the switching circuit.
