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
编辑Vienna 整流器的特點如下:
拓樸
编辑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體電橋,配合整合式的升壓轉換器。
應用
编辑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,可以證明額外硬體成本的合理性時,適合使用Vienna整流器。包括:
- 電信電源
- 不间断电源
- 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]。
