Abstract :
This work presents the operation and design of a high power factor high frequency switching power supply. A good power factor is obtained using as a pre-regulator circuit an AC-DC boost converter associated with a nondissipative snubber operating with high power factor and without commutation losses. The same nondissipative snubber associated with the forward converter is used as the DC-DC converter.
