@tyler: Surely will shared it up and thank you
@liveforphysics: I'll be the "Java Man", well I am in fact a Javanese . Anyway, I'm planning to implement a two phase commit, If I may use the term, i.e. switch all Fet off first, perhaps put a nano second dead time, the switch to next switching arrangement. However, as I don't really have an discrete electronic background (except for computer engineering plus a postgrad in telco), don't really know if this will cater the parasitic capacitance in Fet's gate, so what I'm planning to do is to also implement a fix switch state on the low side and the PWM pulse on the High side which was said to mitigate passthrough at certain degree. Do you suppose a nano second dead time is sufficient ?
On the Fet, the main reason that I'm using the IRF3007 is because it was the biggest Amps & Vds rating available in the clearance sales :lol: . The IRFP4468PBF was quoted for SGD 54.38 each for 290A/100V while mine was SGD 2.24 for 80A/70V, still both Fet have a 4V Vgs threshold I supposed we could just swap it out when needed. Still you are right that it will runs cooler . Perhaps if later on I could get my self a those high amps American alternator might go for this one.
