Abstract:
An electronic stabilizer with single stage conversion, comprising:a push-pull resonant stage including a high frequency transformer and a plurality of 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;a synchronous pulse width modulation controller for sampling signals from the lamp and feeding back to control a power input for the lamp; anda converter comprising a plurality of transistors to form a dynamic resistance that allows current to flow in both directions, the converter including an input end that is electrically connected to an output end of the synchronous pulse width modulation controller, the converter further including 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;whereby there is only one stage of energy loss in the push-pull resonant stage between the power input and the lamp.
