Abstract

Traditional three-phase Buck-type power factor correction (PFC) rectifier typically have a large dc-side inductor, which suppresses the inrush current during startup. However, with the trend towards higher power density, the smaller inductor is often used to replace larger ones on the dc-side. This change results in a significant shift in the startup characteristics of three-phase Buck-type PFC rectifier. Currently, there is little research on startup control strategy for three-phase Buck-type PFC rectifier with high power density. To fulfill this gap, this article investigates the issue of startup inrush current of high power density three-phase Buck-type PFC rectifier. This article provides a detailed analysis of the mechanism behind inrush current generation in three-phase Buck-type PFC rectifiers with high power density. Based on this analysis, a soft-startup scheme and a method for designing its startup curve are proposed to achieve a rapid startup within the safety threshold. Finally, a 4kW industrial prototype is built to verify the effectiveness of the proposed scheme. The test results show that this method achieves a rapid soft startup of the system.

高功率密度三相降压型 PFC 整流器的启动策略

传统的三相buck型功率因数校正（PFC）整流器通常具有较大的直流侧电感，用于抑制启动时的浪涌电流。然而，随着更高功率密度的趋势，在直流侧经常使用较小的电感来取代较大的电感。这种变化导致三相buck型PFC整流器启动特性的显著变化。目前，对大功率密度三相buck型PFC整流器的启动控制策略研究较少。为了填补这一空白，本文研究了大功率密度三相buck型PFC整流器的启动浪涌电流问题。本文详细分析了高功率密度三相buck型PFC整流器产生浪涌电流的机理。在此基础上，提出了一种软启动方案及其启动曲线设计方法，以实现在安全阈值范围内的快速启动。最后，建立了一个4kW的工业样机来验证所提出方案的有效性。测试结果表明，该方法实现了系统的快速软启动。
