DC-DC FLYBACK CONVERTER WITH PRIMARY SIDE AUXILIARY VOLTAGE OUTPUT

摘要

A DC-DC flyback converter includes a transformer and a switching component connected between the transformer and a ground. The switching component controls current flow through the primary winding of the transformer. A snubber circuit is connected between ground and the connection between the transformer and the switching component. The snubber circuit reduces transient voltage spikes across the switching component. A capacitive component of the snubber circuit provides stability for a primary side auxiliary output voltage while maintaining power factor and THD performance.
