    Good Morning All

    can someone tell me if it's possible to use a H bridge type chip
    to drive a pair of thyristors in the manor shown in the attached word doc.

    there are 2 inputs
    one controlling the which thyristor is on and off
    and second input doing PWM.(power control when on)

    the two outputs will drive the thyristors gates

    I want to use a H bridge to safe guard against shoot through etc.

    the application is to run a pair of high current/voltage thyristors for AC TIG welding(running from two independent dc supplies --batteries))

    have included a Tina Ti TSC file zipped up
