Microcontroller_optocoupler_H bridge

hi
I'm working to make a control box of electric car bu using PWM module in
[pic18f452] this will drive a MOSFET H-bridge by using optocouplers

I want to know how i can connect the optocoupler with IGPT mosfet H-bridge
as ,i tried it in PROTEUS but it give error that i could not understand

It shouldn't be that difficult. Most optocouplers have an NPN output transistor that effectively conducts when the led (input) is lit. So all you really need to do is use a pullup from the transistor.

See the example H bridge driver here...

**broken link removed**

You could effectively change all of the transistors here for NPN types with pullups, and change the drive logic so that you get the expected results from your microcontroller.
