PMP22220: My customer want to refer PMP22220 to design Bridgeless PFC .

Hello Jimmy,

PMP22220 is designed for 1kW at lowline input, but you need 2kW universal line.
So you need stronger power stage, another layout and the software needs to be modified,
means a new ground up design.

This bridgeless PFC is made w/ CoolMOS; for a new 2kW design a GaN or SiC based solution
could be a valid starting point; the smaller parasitic capacitances are lowering common mode noise,
so beside better efficiency and smaller thermal interface your filter effort will be lowered as well.

Please check our TIDA-01604, shrinking this three phase PFC to only two phases will match your
requirements, up to 2.2kW at low line input / up to 4.4kW at high line input.
You could reduce output capacitance, because this design is made for variable output voltage 400Vdc
to 600Vdc; for constant output voltage 390Vdc such large capacitance is not needed.

This would be my very first starting point for you, best regards, Bernd

Hello Jimmy,

YES, of course, the software needs modification;
for ripple reduction a three phase system works interleaved w/
120 degrees phase shift in between the phases,
the two phase system works 180 degrees interleaved.

At low line input this helps two reduce ripple stress from
output capacitor of PFC (ripple cancellation at 50% duty).

Best regards, Bernd
