This paper presents an improved approach to detect harmonic and reactive currents in single phase circuit. This method can cancel the double frequency ripples by cross and feedback decoupling. Comparing to the existing methods, the proposed method can effectively improve the detection precision without degradation of the dynamic performance. Simulation and experimental results are provided to validate the effectiveness of the proposed method.
