Patent ID: 7330000

Claim:
A control circuit structured to regulate a supply voltage to a predetermined load, said control circuit comprising: at least one transformer including primary and secondary windings structured to generate fields of opposite polarity, said primary winding connected across the supply voltage and said secondary winding connected in series with at least one discharge bulb defining the predetermined load, at least one switching assembly comprising first and second operative positions and operatively associated with said one transformer, said first operative position comprising said primary winding connected across the supply voltage to induce a voltage of opposite polarity across said secondary winding, said second operative position comprising a disconnection of said primary winding and a shunt thereof to define a zero voltage across said secondary winding, and said at least one discharge bulb comprising a minimum operable voltage; said transformer structured to define a ratio between said primary and secondary windings capable of applying at least a minimally greater voltage to said one discharge bulb than said minimum operable voltage.
