ABSTRACT:
A 50 Hz or 60 Hz AC line voltage is rectified and converted to a DC voltage signal by a fluorescent lamp light ballast system. The DC voltage signal drives a pair of transistors to alternate between ON and OFF states, thereby producing a high frequency signal. A resonant circuit of the light ballast system converts the high frequency signal into a high amplitude, high frequency voltage signal needed to excite a fluorescent lamp load into operation. A protective circuit is employed to stop the generation of the high amplitude, high frequency voltage signal when the lamp load is in a burnout condition or when the lamp load is being replaced.
