摘要
对于广泛使用的三相桥式整流电容滤波电路 ,在直流侧接入电抗器是提高电路输入功率因数降低谐波电流的有效方法。通过分析得出了电路各项输入指标与参数间的理论关系式 ,为电路分析设计提供了有效的工具。
For the three phase capacitive rectifier, which was widely used in the power electronics equipment, LC filter in DC is an effective structure to improve the power factor and reduce the input harmonic current. A theory equation is derived in this paper, which shows the relationship between the input characteristics and the circuit parameter. The correctness of the conclusion is proved by the simulation and the experiment.
