摘要
分别从频域和时域 2个方面 ,分析了非正弦周期电流的分解方法 ,讨论了各电流分量的定义、物理意义、作用以及它们之间的关系。所有这些都是以 Budeanu和 Fryze非正弦条件下的功率定义为线索 ,并结合了其他功率定义思想。所获得的结论为有针对性地补偿非正弦周期电流中有关分量提供了理论依据。
From two aspects of both the frequency domain and the time domain, the decomposition approaches for the nonsinusoidal periodic current are analyzed. The definition. physical meaning and action of its each current component as well asthe relationship among them are discussed, in line with Budeanu's and Fryze's power definitions under nonaisinusoidalcondition, and in combination with the ideas of other power definitions. The obtained conclusions can provide theoretical basisfor relevantly compensating some relative current components in the non-sinusoidal periodic current.
