Hello everyone
I have made an H-bridge circuit using p-type Mosfets (IRF9540) and n-type mosfets (IRF540). My circuit works fine in one direction and drives motors with a reasonable RPM but on reversing the direction, RPM sufficiently decreases to a point where motor is almost not working, mosfets and wires start to heat up. Sparking on battery terminals is also observed.
I m using two BJTS ( C546 and C556B) along with a single optoisolator( 4n25) to drive each mosfet. There are four such units in my h-bridge
Please help me out with this
