| 摘 要： | 鉴于Czarnechi全面否定了Budeanu的无功功率Q_B与畸变功率D_B的定义,本文探讨了Budeanu的Q_B、D_B在一些情况下的适用范围。当电压(或电流)为单次波、而电流(或电压)为非正弦波时,Q_B、D_B的概念能很好的适用;在更一般情况下,经适当修正的Q_B、D_B亦可方便地应用,特别是在电力电子学电路中。最后,本文还讨论了测量Q_B、D_B的方法。

| Abstract: | Due to Czarnecki who has denied Budeanu's definitions on reactive power QB and distortion power DB,the scope of application of Budeanu's QB and DB is deplored. When the voltage u (orcurrent i) is directed or sinusoidal, and the current (or voltage) is nonsinusoidal, the concepts of QB and DB can be applied successfully. In more general situations , the revised QB and DB can be also applied conveniently, particularly in power electronics ciycuits. Finally, the approaches for measuring QB and DB are discussed. |
