1. 1.5KW PFC + LLC (resonant half bridge
Because of the low power, the single PFC + half bridge can satisfy the application, and the circuit is simple and the components are few. MOS is generally 20-50a, 600V, 650V.

2. 3.3kw bridgeless PFC + resonant full bridge
The bridgeless PFC needs 2pcs MOS and 2pcs rectifiers, so there is no need to input rectifier bridge, because there is no input rectifier loss. But EMI is more difficult to deal with. The resonant full bridge needs 4 pcs MOS, and the driving circuit is complex, so it is suitable for high power occasions.

3. 6 ~ 15kw Vienna Three Phase PFC + three level resonant full bridge                                      
The circuit is very complex and needs special drive and control circuit. The advantage is that MOS can be 600650v, which is easy to purchase. Due to the use of multiple MOS, the heat is evenly distributed, and the heat dissipation will be better handled.
