Hello!
I have a problem with driving DC motor in full bridge. I use PIC16F873 to control the module. It produces PWM of 1000Hz with duty cycle of 10% up to 60%. My motor works on 160V DC and I put it into a full bridge but when I wanted to start it nothing happened. Upper two transistors (IRF4PC40AF) and their driver ICs (HCPL3150) burned up. I made EXACTLY as stated in scheme provided by microchip and now I don't know what to do.
Anyone who can help me ? Thanks in advance.
