Abstract:
An electric power supply includes a totem pole bridgeless PFC power converter. The PFC power converter includes an input for coupling to an AC power source, an output, four switching devices coupled between the input and the output, two diodes coupled between the four switching devices and the input, a first inductor coupled between the four switching devices and the two diodes, and a second inductor coupled between the two diodes and the input. Other example electric power supplies and totem pole bridgeless PFC power converters are also disclosed.
