Dear All. I have been busy last week designing MOSFET H-BRIDGE SWITCH for my 24V DC GEARED motor. I started with EUGENE BLANCHARD (P & N MOSFET FULL BRIDGE available on net) but my P-channel Mosfet were blown. I changed the circuit for GATE TO SOURCE voltage of less than 12V by adding resistive divider & 12v zener at gates but still no result. Third time i decided to make a test circuit as HALF BRIDGE but without pulling P-channel mosfet gate LOW the MOSFET is condutcting 24V. I tried same circuits with 12V supply but still no luck. I am using IRF9540 & BUZ11 MOSFETs. I have been busy reading your posts regarding H-BRIDGE & their gate drivers, but i am becoming so much confused that i am forced to write my problem to u guys. In short i just need to drive my 24VDC GEARED MOTOR in FORWARD & REVERSE DIRECTION without PWM. Or please guide me if i should be using PWM in this case. Also i dont want to use RELAYS for this job :-(
Hope to recieve quick & positive replies from you guys. Thanks in advance to all of you. Regards
 
If you're having this much trouble creating an H-bridge you should probably stop and buy a module instead. You'll need to post complete schematics of all circuits you've tried and their results not just brief text description if you need further assistance.
