Abstract
A power supply device for a gas filled arc-type lamp having a transformer with a core with a primary coil and a secondary coil, a power source coupled to the primary coil of the transformer core and providing a generally sinusoidal signal, a connector for joining the secondary coil of the transformer to the gas-filled arch-type lamp, and an unbalanced capacitance for introducing even-order harmonic distortion on the generally sinusoidal signal on the primary coil of the transformer and generating a generally sinusoidal signal on the secondary coil of the transformer such that a flow of ionized gas is created within the gas-filled arch-type lamp for dispersing any bubbles and standing waves in the lamp and so as to avoid adjustment of the power supply. The distorted signal has one-half cycle longer with a lower peak voltage than the other half-cycle.
