IGBT and MOSFET

[evilsanta]

Anyone able to tell me how these control the speed of a DC motor?

Are they a faster way of switching thyristors? Do they store certain amounts of voltage and only allow through what you want it to?

Been at this question for the last couple of days now and cant seem to find an explanation on the internet of how it actually performs, or maybe I am but im not realizing it. Or if you can point me in the direction of a book that would be great.

Thanks in advance

hi there

Google circuits for PWM and H-bridge control of DC motor

you should get many hits
