单桥电流源型整流器功率因数控制技术的研究

Sdudy of Power Factor Control Technology for Single-Bridge Current Source Rectifier

以单桥电流源型整流器为研究对象,介绍了一种新颖的功率因数控制技术。通过分析给出了控制策略框图,具体阐述了控制思想。采用本文的控制方法,可以使单桥电流源型整流器以单位功率因数或最大功率因数运行。实验结果验证了该方法的正确性。

This paper makes an investigation with single-bridge Current Source Rectifier （CSR）, introduces a novel Power Factor Control （PFC） technology. The paper gives the block diagram of control scheme via analysis, moreover expatiates control idea concretely.The single-bridge CSR can potentially achieve a unity or maximum power factor operation adopting the control method.At last, the experimental results prove that the control method is correct.
