The present solid state device generates variable interval, high frequency bursts of alternating current to dim or otherwise control a discharge lamp or the like, and features an adjustable duty-cycle burst control subcircuit that intermittently interrupts a pair of constant, phase-reversed, high frequency pulse sequences, thereby permitting variable interval bursts of the pulse sequences to reach a pair of semiconductor devices. The semiconductors alternately switch ON and OFF in response to the high frequency pulses applied thereto, thereby rapidly alternating the direction of current flow through a suitable inductor configuration which, in turn, is connected to the load.
