Hai, I have design unipolar stepper motor diver. In that when on one phase FET at chopping frequency rate, it turn on other phase FET in the same coil. The same condition is for with freewheeling and without freewheeling diodes. When freewheeling diode put, circuit draws more current than without freewheeling.
Help me for find correct problem, and how can overcome.
Thanks for your help.
