Abstract :
An improved quick detection method for fundamental wave and harmonics in single-phase AC source is presented. Single-phase inverter produces amount of harmonics, which directly affect the quality of electric energy[1-3]. This paper propose an improved method, which can fully detect the fundamental wave and harmonic. The method applies orthogonal transformation theory. The principle is demonstrated, and the results of Matlab simulation is presented to verify the validity of proposed theory.
