hi
i want to design circuit to drive an speed control for single phase AC-motor
P=1.5hp
v=220 v
f=50hz
i want to control it using PWM . the signal of PWM come from PIC16F877A
that signal will trigger the power element that used(IGBT,MOSFET)
am need help in design that circuit also how to use the signal from PIC(5V,20mA) to trigger power element(high cureent)?
