    Hi there,

    I have some questions regarding DCtoAC Inverters which give
    out modified sine wave output.I know that the output looks like a
    square wave with its edges rounded off which comes out at 50Hz or
    60Hz.What will be the frequency of the highest harmonic present in the
    output.Will a 1KW Inverter be able to drive a 1HP single phase AC
    motor load or what do I need to make it run.I cant afford
    pure-sinewave inverters.

    And also I want to rectify the output of the inverter to DC by
    using normal bridge modules and high capcitance capacitors as
    filters.I know I'll be getting around 350V or so. Will I be able to
    run DC motors from the DC supply provided that motor power
    requirements are met by the inverter.

    I think if it can be converted to DC with normal rectifier
    bridges(I mean I don't have to use any high recovery diodes to recitfy
    such high frequency outputs)and make DC motors run it would be better
    cause the high amount of harmonics present in the quasi-sine inverters
    will damage the single phase AC motors.

    Thank You,
