【摘要】 基于瞬时功率概念，针对单相交流电路提出了新的功率成分定义。各种功率成份都有明确的物理意义并与功率过程直接相关。该功率定义适用于直流、交流正弦和交流非正弦等电路，对非有功功率补偿器的选择和设计具有指导意义。更多还原

【Abstract】 Novel concepts of power components in single - phase AC circuits based on instantaneous power con- cept are proposed Every kind of power components advanced is concerned directly with instantaneous power process in circuit and possesses clear physiscal meaning . This power component definition is suited to DC, AC sinusoidal and AC nonsinusoidal circuits, and it is important and usefull for the choice and design of non - active pwer compensators .更多还原
