1. An AC driver circuit for providing an improved output current regulation to a gas discharge load, said driver circuit comprising:

  • a square wave inverter circuit for generating a square wave voltage, a resonant circuit including a series inductor and capacitor, said capacitor being connected across said load, a current comparing toggling circuit (CCTC) for sensing current to said resonant circuit and commutating the inverter state whenever the input current to said resonant network is equal to a selected current of said load.
