I'm looking to do a Motor Control Circuit using a PWM signal as show in this video (

). Can I use a hyperfast rectifier in place of the MOSFET thats used.

thanks

 

What sort of 'hyperfast' rectifier? An SCR might work, but would require added circuitry to switch it off.

 

A 'hyper-fast rectifier' seems to be just that: a rectifier. You need a three-terminal device for control
