Abstract The electronic ballast of energy-saving lamp has several characteristics，such as high efficiency，energy-saving，no f lash，no noise and so on. It can also start rapidly at the low voltage. So they are widely used. But as a result of the components selection，design and other factors，the electronic ballast has higher fault rate. By discussing the structure and operating principle of the low power electronic ballast being used in daily life，the reasons of several kinds of typical fault that frequently occurs are analyzed，so that the fault point can be found quickly and some improvements can be made.
