hi there
I have a mosfet h bridge design which works with a passive load of 3 amps @300vdc.
therefore p=v x i = 300 x 3 = 900 watts
so the whole circuits power disspation = 900 watts
how do i work out the power going through the mosfets?
is it 900 watts or is it P=I² x Rdson = 3² x 0.27 = 2.43 watts
which means that 2.43 watts is going through the mosfets and the rest in the passive load??
