    i need to determine switching angles to drive switches at specific angles,as a result H-bridge inverter will give a sinwave at its output.
    How can i find those switching angles?
    Thanks in advance :)

    Can you please elaborate?
    The problem here is your H-Bridge... They are not typically operated in a linear manner...
    If they were, there would be HUGE power losses in the transistors (FETs) .
    Typically the sine wave is approximated with PWM... Passive filter components can be installed to help smooth out the 'steps'.
