摘　　要：针对太阳能高压钠灯电子镇流器的特点和高压钠(HPS)灯在高频下的缺陷,设计了一种基于廉价驱动芯片SG3525A为基础的新颖太阳能高压钠灯电子镇流器,采用频率调制技术消除了声共振。设计了可靠的启动电路及过流、过压和异常保护电路,能实现恒功率控制,最后给出了实验结果。Aimed at the characters of solar energy electronic ballast and the lack of HPS with high frequency, the paper described a new high pressure sodium lamp based on the half bridge driver SG3525A, one kind of cheap chip, which adopted the variable frequency technology to avoid acoustic resonance.It could output constant power, reliance start,over-current,over-voltage etc protections. The results of the experiment were given in the paper.
