Totem-Pole Bridgeless PFC (Synchronous FETs)
This is a Totem-Pole Bridgeless PFC with MOSFETs on the low-frequency side, which can achieve even higher efficiency and bi-directional operation by changing the control method.
The switch acts as a boost converter when the input voltage is positive and negative half cycle respectively. The totem pole structure solves the recovery loss problem of rectifier diodes.
- Single stage PFC
- Low frequency leg with SJ MOSFETS for higher performance
- Efficiency higher than 99%
- Frequency from 48 to 150 kHz
