I am trying to drive a 24 volt dc 300 watt dc motor. Using a pwm frequency of 1 kHz. I have tried multiple designs of mosfets, and transistors but they keep blowing up due to the inrush current 20 amps. Or maybe something going on with the micro-controller. But I found a design that worked for a while but was not large enough(4transistors). So I ex

I need a variable power supply to control 2 H bridges which drive 2 DC motors. The max output current and voltage is 5A and 20V respectively. I have designed the following circuit based on Dave Jones's lab supply where the output voltage and current is set by filtered pwm signals.
What can I do to improve the stability and quality on
