I'm posting this on behalf of a colleague. We're working on a high frequency (20kHz) PWM application and are looking at connecting a free wheeling diode to the circuit. We need some guidance on how to calculate the average forward current and maximum current that this diode might see. Also, if anyone has any tips on calculating the heat dissipation by the diode, that would be helpful as well. Thanks.
