This paper presents a modification of the Vienna rectifier (VR) to obtain more than three voltage levels at the DC line connection, while preserving the unity power factor at the AC grid side. The proposed unidirectional multilevel there-phase rectifier, called the “Negev rectifier”, has a reduced device count and utilizes a unique novel Time Division Multiplexed based control scheme, which makes the challenging N-level VR expansion possible. The Negev rectifier can serve as a grid interface for supplying dc voltage to multilevel inverters with 4 up to 7 voltage levels, eliminating the burden of inverter-side voltage balancing control. The Negev hardware can be constructed by two complementary topologies, making it suitable for either high current or high voltage applications.

新型有源三相多电平功率因数校正前端的建模与仿真——“Negev”整流器

本文介绍了对 Vienna 整流器 (VR) 的修改,以在直流线路连接处获得三个以上的电压电平,同时在交流电网侧保持单位功率因数。所提出的单向多级三相整流器,称为“Negev 整流器”,减少了设备数量,并利用了独特的新颖基于时分复用的控制方案,这使得具有挑战性的 N 级 VR 扩展成为可能。Negev 整流器可作为电网接口,为具有 4 至 7 个电压电平的多电平逆变器提供直流电压,从而消除逆变器侧电压平衡控制的负担。Negev 硬件可以由两种互补的拓扑结构构成,使其适用于高电流或高电压应用。
