摘要
以Budeanu非正弦条件下的功率定义为线索,结合其它功率定义的观点,从频域分析了非正弦周期电流的分解方法,讨论了各电流分量和对应功率分量的定义、物理意义、作用以及它们之间的关系.在此基础上,提出了非正弦周期电流相关分量的一种实时检测方法,构造了相应的检测电路,研究了电路的特性.最后进行了仿真和实验研究.
Regarding Budeanu's power definition under nonsinusoidal condition as the clues, and joining the viewpoint of other power definitions, the decomposition approach for the nonsinusoidal period current was analyzed from frequency domain, The definitions, physical meanings and actions of its correlative current components as well as corresponding power components, and the relationship among the components were discussed. Then the detection approach of the correlation components in nonsinusoidal period current was proposed, the homologous detection circuit was constructed and the circuit traits were investigated. Finally, the simulation and the experiment investigations were done.
