Need help with MOSFET h-bridge; gets hot when using PWM frequency of ~500Hz. Answered
I recently bought an Arduino and used it to control a MOSFET h-bridge circuit.Everything worked fine until I started using PWM to drive the motors.The PWM frequency is about 500 Hz and I've already tried switching out the 1N4004 flyback diodes in the h-bridge circuit for 1N5819 shottky diodes but it didn't help. The schematic of the h-bridge can be found here ( https://cdn.instructables.com/FDQ/NF1D/GWF60U03/FDQNF1DGWF60U03.MEDIUM.gif )
What should I do?
