摘　　要：以一个控制系统为基础分析了自激LC串联谐振并联负载型电子镇流器的工作原理。将该电子镇流器视为一个理想的继电型的非线性系统 ,并对其控制特性作了详细的分析。运用描述函数法和推广的奈魁斯特稳定判据等工具设计了一个 36W自激LC串联谐振并联负载型电子镇流器。From the view point of a control system,the principle of a self oscillating LC series resonant parallel load inverter for electronic ballasts is analyzed.The electronic ballasts can be treated as an ideal non linear relay system and its control model is analyzed in detail.Then,the design of self oscilating electronic ballast using control tools such as description function,extended Nyquist criterion has been carried out.Experimental results show the method is efficiency and available.
