1. A soft switched PWM AC to DC converter, comprising:

  • a power factor corrector converter with a boost topology that operates at a first fixed frequency;

    a DC/DC converter with a forward topology that operates at a second fixed frequency;

    a clock that operates at a fixed frequency that is greater than the frequency of the first fixed frequency and the second fixed frequency; and

    a gate array logic IC for timing and synchronizing PWM signals for the power factor corrector converter and the DC/DC converter using the clock signal, whereby the clock signal is divided "n" times in the gate array logic IC using a synchronous divider to provide virtual monostable output signals for use in converter synchronization and gate signal timing.
