| 摘 要： | 在电子镇流器及节能灯中，无源功率因数校正电路具有成本低，可靠性好，调试容易等优点，但往往在谐波含量问题上迭不到电磁兼容标准的要求。下面对无源功率因数校正的几种实现方法进行了对比分析，并延深出了一种新的实现方法，可使无源功率因数校正电路的谐波含量降到15％以下，功率因数不小于0．96，满足电磁兼容标准要求，在实际应用中可供借鉴。

| Abstract: | In electronic ballast and energy saving lamp, the passive power factor correction （PFC） circuit has the advantages of low cost, high stability and easy debugging, but its harmonic content often fails to meet the requirement of EMC standard. With the comparison and analysis of several ways to realize the passive power factor correction, a new method was found. It can decrease the harmonic content to less than 15 %, make the power factor less than 0.96 and meet the requirement of EMC standard. |
