摘要
Abstract
The circuit by the current of passive power factor correction is widely applied in china, because of its low cost and good performance, but the circuit has relatively high harmonic current so that the power factor can't be further improved and can't meet the requirement of higher electromagnetic compatibility.A modified circuit by current to improve the passive power factor correction is proposed.Taking 28 W fluorescent lamp as the load, the experimental analysis and study are carried out with contrast method.A result that further decreased harmonic current, improved power factor and met the requirement of electromagnetic compatibility in the case of not increasing cost was obtained by the modified passive power factor correction circuit by current.关键词
