there is no standard circuit to start from. i was hoping something as simple as a 555 ic and it'll be controlling the H bridge mentioned in the other post. for simplicity i just built a standard h bridge for now out of uprated parts, the H-bridge and the P.w.m. will be a separate chip from the...

tnx for the help, it's finally clicked

any body have a good design for a p.w.m that has a adjustable start current and ramp up time

large 1:4 scale r/c car and use a LOT of current the difference in the internal resistance was becoming a problem in heating, and srry it was n types just i was typeing without thinking

i'm using p type mosfets for an r/c cars h bridge controller (the two n types have been replaced with p types because of their lower internal resistance) and was wondering if there is a way to do it without voltage pump circuits that stills alllows a P.W.M. torque controller.

why would you be using mosfets for logic gates, correct me if I'm wrong but aren't they generally used for power handling

if some one could help me understand the difference between the math used to find the reactive powers voltamps and reactances ohms

not series parallel you are using the cap to store the active power from inductor effect of the motor windings and supply it back as reactive power. so the capacitor has to be in parallel
