Abstract
An electronic stabilizer with single stage conversion includes a push-pull resonant stage, a synchronous pulse width modulation controller, and a converter. The push-pull resonant stage includes a high frequency transformer and transistors to form an alternating voltage-increasing loop that operates under self-activating oscillation, the high frequency transformer including a secondary winding for driving a lamp. The synchronous pulse width modulation controller samples signals from the lamp and feeds back to control a power input for the lamp. The converter includes transistors to form a dynamic resistance that allows current to flow in both directions. The converter includes an input end that is electrically connected to an output end of the synchronous pulse width modulation controller. The converter further includes an output end that is electrically connected in series to the secondary winding of the high frequency transformer and in series connection with the lamp. Only one stage of energy loss occurs in the push-pull resonant stage between the power input and the lamp.
