维也纳整流器

Vienna整流器（英语：Vienna rectifier）是脉冲宽度调变的整流器，可以接收三相交流电源，也是功率因数修正电路，是Johann W. Kolar在1993年发明^[1]。

特点

Vienna 整流器的特点如下：

三相三电平的PWM整流器，其中包括三个功率晶体，可以控制输出电压^[2]。
输入只需要三条电源线，不需要连接对应中性点的线
主回路维持电阻特性^{[来源请求]}
升压式架构（输入电流连续）
单向的功率流动^[3]
高功率密度
低的导通共模EMI噪声
要控制使中性点电压稳定，比较简单^[4]
低复杂度，实现成本低^[3]
低导通损失^[5]
在电源三相不平衡，或是电源失效时，仍有可靠的行为特性（保证有类似电阻的特性）^[6]

拓朴

Vienna整流器是三相三电平的PWM整流器。可以视为是三相的二极管电桥，配合整合式的升压转换器。

应用

Vienna整流器可以用在任何有用六个开关的转换器，希望产生弦波输入电流以及可控电压输出的情形，而且能量不需回灌到电路的应用下。在整务上，若有足够空间，可以证明额外硬件成本的合理性时，适合使用Vienna整流器。包括：

电信电源
不间断电源
交流驱动器的交流输入端

右图有风冷10 kW Vienna整流器（载波频率400 kHz），有弧弦波输入电流以及可控输出电压。大小是250mm x 120mm x 40mm，功率密度是8.5 kW/dm³，总重2.1 kg ^[7]。
