Abstract

This paper proposes a novel detection method of active and reactive currents in single-phase circuits. This method uses only two multipliers and LPFs for detecting active and reactive currents with a PLL circuit. In the proposed method the fundamental active-reactive component in single-phase circuits can be detected by LPFs in the time domain like the instantaneous active-reactive power theory in three-phase circuits. The basic principle of the proposed detection method is discussed in detail, and then confirmed by digital computer simulation. Digital computer simulation results demonstrate that the proposed method can detect the active-reactive current in single-phase circuits in the time domain.
