400W太阳能高压钠灯电子镇流器的研制

Research of solar energy electronic ballast for 400W high pressure sodium lamp

针对太阳能高压钠灯电子镇流器的特点和高压钠灯在高频下的缺陷,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。并且设计了可靠的启动电路及过流、过压和异常保护电路,且能实现恒功率控制,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 describes 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 can output constant power、reliance start、over-current、over-voltage etc protections and it gives the ends of the experiment.
