Abstract:
A fluorescent electronic ballast including: a rectifier circuit, for receiving an AC power supply and converting the AC power supply into a DC power supply; an inverter circuit, coupled to a fluorescent driver circuit, for converting the DC power supply into a high-frequency AC power supply for driving a fluorescent; and a detection protection circuit, coupled to the rectifier circuit and the inverter circuit, for detecting the DC power supply provided by the rectifier circuit, and cutting off the electric connection between a control chip of the inverter circuit and all of power supply when the voltage of the direct current power supply is lower than a predetermined value, wherein the power supply at least includes the direct current power supply provided by the rectifier circuit.
