HomeMade Motor Controllers

[John Gutmann]

I know that the Victor series motor controller is complex, but i wanted to venture into the unknown, and make something i haven't made yet(that being hard with how much i have done) and i was wondering what kinda of transistors were used in the Victors to obtain such high current potential, and if anyone knew a function control flow chart for it: IE does it amplify the pwm signal then use it or just use it straight from the source

The transistors used in it, are the FETs or MOSFETs, i was thinking one of those since they do not hold their state for long and need to be refreshed in a cycle (such as in DRAM)?

for the transistors to withstand the curent are they in series?

and for my own should i use a heat sink and a fan or just a fan, beacause if possible i would like to get the TO-220 package so it has some built in surface area for power diapation

and my PCB how do i make a PCB to stand up to about 50 amps or more?


thanks
