ABSTRACT:
A high frequency converter for driving a gas discharge lamp load is comprised of an input stage for receiving an AC input voltage and rectifying the input voltage to create a DC voltage source, an oscillating power inverter, an output stage connected to the power inverter, and a trigger circuit used to initiate oscillations in the power inverter. The trigger circuit further comprises a voltage ramp circuit. The output stage includes a transformer having a center tap and two capacitors of equal value connected from the tap to each end of the transformer. The capacitors and transformer form two resonant tanks. Also, an RF choke may be connected between the center tap and the source of DC voltage.
