Abstract :
This work presents the operation and design of a high power factor AC-DC-AC power supply rated at 2 kW operating at high switching frequency. Good power factor is obtained using an AC-DC interleaved boost-flyback converter as a pre-regulator circuit associated with a nondissipative snubber without commutation losses. Commutation losses are practically reduced to zero and EMI emission can also be minimized. The operation of the ZCZVS PWM full-bridge inverter operating at 30kHz in the high frequency leg and at 60Hz in low frequency leg is also investigated.
