    Hello,

    I have an inverter circuit, although I learn that hooking a load
    directly to its output is not working.
    I was not sure if I should use an opAmp or mosfet, I have the circuit
    below, any improvment? anybetter way to do it. The load I want to add
    is to drive a mosfet
    Yes some people will say not to use the same power supply on both
    sides of the optocouplers ,but this is just for the simulation.

    your simulation is ok?

    yep, turn on and off the 5v supply on the left and the assigned mosfet
    turns on and off. I posted the same circuit twice with the two
    possible conditions.
    to show that is works. Is there a way to reduce the current that goes
    into the opto? without affecting the output, maybe replace the opto...

    I will be driving this from a microcontroller, I could not get a good
    software approach, to get the duty cycle synchronyse. It is better to
    do it hardware. I might make the output of the micro drive a 2n2222 to
    activate the opto, then I will have to find a solution to control the
    other opto.

    I just need 50%, one mosfet turns on the first half and the other
    turns on the other 50%, therefore always one turned on.
    (In a microcontroller I could not get only the second half to
    activate)

    power transfered is during rise and fall not duty cycles. and why using optocoupler if you intend to drive them from a common PS. lame idea.
