三相相模块隔离功率因数校正整流器是相集成三相整流器的一个有趣的替代方案，因为矩阵型相位模块允许在三相电源和直流母线之间进行单级隔离能量转换。因此，本文提出了一种相位模块化隔离矩阵型整流器，它可以以星型(Y)或delta型（$\ delta $）配置连接到市电，从而实现宽输入电压范围。此外，这允许根据所使用的半导体技术选择相模块开关的电压和电流应力，例如${\text{650 V}}$ Si或GaN器件可用于从${400}$或${\text{480 V}}_{\text{rms}}$电源供电的整流器。详细分析了变换器的工作原理和开关行为，表明在相位模块中可以实现零电压开关。此外，提出了一种三次谐波电流注入概念，该概念允许在$\Delta$ -模式下高达${15}\%$高输出电压。通过在${\text{7.5}}\；{\文本{千瓦}}$,${\文本{400}}\;{\text{V}}$直流输出电压原型转换器在额定功率下实现${97.2}$效率和$总谐波失真。
Three-phase phase-modular isolated power factor correction rectifiers are an interesting alternative to phase-integrated three-phase rectifiers as matrix-type phase modules allow a single-stage isolated energy conversion between the three-phase mains and a dc bus. Therefore, this paper presents a phase-modular isolated matrix-type rectifier which can be connected to the mains either in star (Y) or delta ( $\Delta$) configuration, enabling a wide input voltage range. Additionally this allows to select the voltage and current stresses of the phase module switches according to the used semiconductor technology, for example ${\text{650 V}}$ Si or GaN devices could be used in rectifiers powered from the ${400}$ or ${\text{480 V}}_{\text{rms}}$ mains. A detailed analysis of the operating principles and switching behavior of the converter is presented, showing that zero voltage switching can be achieved in the phase modules. Additionally a third harmonic current injection concept is proposed which allows an up to ${15} \%$ higher output voltage in $\Delta$ -mode. The concepts are validated with measurements taken on a ${\text{7.5}}\;{\text{kW}}$, ${\text{400}}\;{\text{V}}$ dc output voltage prototype converter achieving ${97.2} \%$ efficiency and a total harmonic distortion of $ at rated power.
