description The utility model relates to a high power electronic ballast with high output power and low temperature-raising, which comprises a rectification circuit, a filter circuit, an inverter circuit and a series resonance circuit. The utility model is characterized in that: the semi bridge in the inverter circuit adopts two or more than two dynatrons in parallel as the power output circuit. The base and the emitter of the dynatron are respectively connected with a current equaling resistance in series, thus making the heat to each dynatron be consistent to improve output power of the ballast.
