摘　　要：根据高压钠灯的电气特点开发出相应的电子镇流器,主电路采用半桥式电荷泵逆变电路。该电路的特点是将功率因数校正与逆变电路融合在一起。控制器采用模拟PI调节器电路与单片机相结合实现灯的恒功率控制和钠灯的启动控制。给出了灯功率为110W,工作频率为30kHz条件下的实验结果。The electronic ballast for high-pressure sodium lamp is developed.The main circuit topology of the ballast had adopted a charge pump half-bridge inverter with power factor correction.The controller composed of analog PI regulator and single chip microcomputer to realize constant lamp power and to fire lamp.The experimental results obtained form 110W high-pressure sodium lamp operating at 30kHz switching frequency are also presented.
