N2 - This paper proposes an interleaved totem-pole bridgeless boost power factor correction (PFC) converter employing an additional inductor which has small switching loss. The main problem of conventional interleaved totem-pole bridgeless boost PFC converter is large switching loss due to the hard switching operation. And that problem becomes more serious in high switching frequency operation. In proposed converter, by utilizing the energy of additional inductor, zero-voltage-switching (ZVS) operation of the switches is achieved. Also, by using phase-shifting control between two interleaved PFC units, the flowing current on additional inductor can be controlled and only proper magnitude of current is generated. As a result, the proposed converter has higher efficiency than conventional converter. The feasibility of the proposed converter is confirmed with 50Hz, 230Vrms input and 1.6kW (400V / 4A) output prototype.
