Hi all,

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 this design? Can someone recommend a better power transistor for this as I find it a little hard to choose one. Your input will be most valuable.

Regards
