Abstract

This work presents the operation and design of a high power factor high frequency switching power supply with a power of 2 kW. A good power factor is obtained using as a pre-regulator circuit an AC-DC interleaved boost-flyback converter associated with a non-dissipative snubber operating with high power factor, switching in 100 kHz and without commutation losses. The same non-dissipative snubber associated with the full bridge, switching in 100 kHz converter is used as the DC-DC converter.
