維也納整流器

Vienna整流器（英語：Vienna rectifier）是脈衝寬度調變的整流器，可以接收三相交流電源，也是功率因數修正電路，是Johann W. Kolar在1993年發明^[1]。

特點

Vienna 整流器的特點如下：

三相三電平的PWM整流器，其中包括三個功率晶體，可以控制輸出電壓^[2]。
輸入只需要三條電源線，不需要連接對應中性點的線
主迴路維持電阻特性^{[來源請求]}
升壓式架構（輸入電流連續）
單向的功率流動^[3]
高功率密度
低的導通共模EMI雜訊
要控制使中性點電壓穩定，比較簡單^[4]
低複雜度，實現成本低^[3]
低導通損失^[5]
在電源三相不平衡，或是電源失效時，仍有可靠的行為特性（保證有類似電阻的特性）^[6]

拓樸

Vienna整流器是三相三電平的PWM整流器。可以視為是三相的二極管電橋，配合整合式的升壓轉換器。

應用

Vienna整流器可以用在任何有用六個開關的轉換器，希望產生弦波輸入電流以及可控電壓輸出的情形，而且能量不需回灌到電路的應用下。在整務上，若有足夠空間，可以證明額外硬件成本的合理性時，適合使用Vienna整流器。包括：

電信電源
不間斷電源
交流驅動器的交流輸入端

右圖有風冷10 kW Vienna整流器（載波頻率400 kHz），有弧弦波輸入電流以及可控輸出電壓。大小是250mm x 120mm x 40mm，功率密度是8.5 kW/dm³，總重2.1 kg ^[7]。
