【Abstract】 Based on the adaptive noise suppression principle an improved adaptive harmonic current detecting method is proposed. The method has many advantages, for example, simple structure and algorithm, low cost and perfect real time detecting effect and it can detect harmonic when the voltage waveform of power source distort. A satisfactory detecting precision of the adaptive detecting method can be achieved by selecting the appropriate integral gain k. Simulation results confirms the validity of the proposed method.更多还原
