Breezy Posted July 16, 2010 Report Share Posted July 16, 2010 Hi all. Thank you much for the help you have given to me about PWMPWM_Speed_Controller.zip Quote Link to comment Share on other sites More sharing options...

Kevin Weddle Posted July 20, 2010 Report Share Posted July 20, 2010 An 80A pulse width modulator is too high of amperage for any that I've seen. I'm sure your refering to high voltage and a low impedance. But either way it's going to be a larger circuit. Logic devices and reactive components are used to produce the initial PWM signal Quote Link to comment Share on other sites More sharing options...
Hero999 Posted July 20, 2010 Report Share Posted July 20, 2010 >80A is PWM pretty common in motor control circuits for small electric vehicles such as golf buggies. Large vehicles such as cars require surges of over 1kA but they normally uses AC motors rather than DC. Quote Link to comment Share on other sites More sharing options...
indulis Posted July 23, 2010 Report Share Posted July 23, 2010 An 80A pulse width modulator is too high of amperage for any that I've seen.VRM's go even higher... ~100ABut either way it's going to be a larger circuit.Not really!http://news.thomasnet.com/fullstory/Voltage-Regulator-Module-is-Intel-VRM-11-0-compliant-818760 Quote Link to comment Share on other sites More sharing options...
