    I can't get the full wave waveforms. I keep getting the errors.:confused: Can someone help me to see if there is any error in it? Actually i don't really know how to switch on the MOSFET so maybe it is wrong. So, i hope to get some suggestions from u all. Thank you.:p

    Hello,

    Can you show us the pulse timing?
    The gate pulses should be relative to the source of the fet and be about 10 Volts.

    Hello Bertus,

    I had attached the content of the pulse. You mean the pulse timing, is it the frequency. Actually for the pulse frequency and source frequency, how are they related??

    Hello,

    I am not familiar with ISIS, but I know the fets may NOT be on at the same time.
    When both fets are on, they will blow.
    There should be some "dead" time between the pulses.

    yea..Both will not on at the same time. The problem is when i simulated the circuit, i keep getting errors something like step time too small.
