Abstract

An electronic ballast is disclosed, comprising a rectifying circuit able to rectify and convert the AC power source into a first DC voltage and output a first DC current; a power factor correction voltage circuit able to adjust the phase of the first DC current to enable it to be close to the phase of the first DC voltage and to make the first DC voltage transform, convert and output a second DC voltage; and a full-bridge converting circuit converting the second DC voltage into the AC voltage being infused into the tube. A power detecting circuit is able to control the electric power adjusted by the power factor correction voltage circuit and outputted to the tube. The phase detecting circuit can detect the phase transition of the AC power source and control the full-bridge converting circuit to enable the voltage of the tube to switch the phase according to the frequency that is one part of the positive integer of the baseband of the AC power source.
