摘要
从分析交流正弦电路的瞬时功率出发,提出新的功率成分定义,各种功率成分都有明显的物理意义,该定义可扩展到非正弦交流电路,对电力有源滤波器的设计具有指导意义。
Based on analysis of instantaneous power in AC sinusoidal circuit, new concept of power components is proposed. All kinds of power components possess clear physical meaning. This definition of power components can extended to AC nonsinusoidal circuits. It is of great importance to the design of active power filter.
