Hello there,
I am trying to controle the speed of an AC motor by a PWM controllers.
My questions are:
1: Do I need to use a H-bridge circuit to drive the motors?
2: Can I do so without an H-bridge driver too?
3: Does the H-bridge supplys ideally 2x of the power supply for the motor or just x?
4: If I need a H-bridge for the said motor does it make any fifference to use 4 IRF540 or do I need 2 Nchannels and 2 Pcahnnels mosftes? Any difference?
Thanks
