    MOSFET heating problem in H-bridge

    OK I check signal at DSO and find that my upper lever MOSFET voltage from source to gate is not getting more than 2VDC, according to MOSFET use in H-bridge, voltage between source and gate should be more than 6VDC to get MOSFET fully ON.

    MOSFET heating problem in H-bridge

    As you can see Image, there is in each Image written q78, q98, q109 and on same Image you can find circuit diagram of H-bridge where you get Q9,Q10 and Q7, Input signal to gate for each MOSFET is shown in DSO image.

    MOSFET heating problem in H-bridge

    In attached image can be seen that 3 MOSFET is getting ON in which one is with opposite face.well according to logic only two MOSFET have to get ON, which are diagonally opposite.
