Abstract
In electromagnetic compatibility experiments, harmonic current over-criterion phenomenon often exists in the equipments with bridge rectifier filtering circuit. The causes of harmonic current were found out by analyzing this over-criterion phenomenon. Two solutions which are passive power factor correction and active power factor correction are proposed. The advantages and disadvantages of the two methods are analyzed. The experiments proves that the passive power factor correction method can reduce the harmonic current of about 10 dB, and the active power factor correction method can reduce the harmonic current of about 20dB. The two methods can make the original over-criterion equipment to meet the standard requirements. The availability of the two methods was verified.关键词
