RD-8517 ABSTRACT OF THE DISCLOSURE A variable frequency AC source drives a gas discharge lamp which is connected in parallel with the capacitance of a series resonant circuit. The polarity of the voltage applied to the resonant circuit is commutated at such times as the rate-of-change of current flow in the resonant circuit is at or near zero. The source frequency is thus maintained at or near the circuit resonant frequency to maintain high output voltage when the lamp is starting or reigniting. The polarity is also commutated at such times as the current flow from source reaches a predetermined level. Lamp current is thus controlled in the running mode.
