I'm talking about your circuit diagram. It mentions NPN and PNP transistors.
For the MOSFETs, any high power complementary pair will do. Usually you'll want MOSFETs of the same family.
Depends on how much power you are going to be using, and how much heat and efficiency you are willing to sacrifice for price, size, package, heatsink, etc.
If you want say 120W output power, given 80% efficiency, you will need 150W, which is 12.5 amps.
The IRF9530 P-channel has a 0.2 ohm Rds(on), which is quite high; it's rated for 14A. At the given 12.5 amps, it dissipates 31.25 watts approximately. This is below its package rating of 79 watts. A good heatsink WILL be required or the MOSFET will burn in seconds. This is not taking into account the switching dissipation, but if it's a 50Hz or 60Hz signal, that will be small, I think.
I mention this MOSFET because I am familiar with it and have a few spare...
Anyone know what the complementary of the IRF9530 is?
