| Abstract: | A detection method for phase changed points and phase sequences for the controlled rectifier circuit based on digital circuit is proposed.The phase changed points are detected through sampling the voltage with a high frequency by the digital circuit,which is verified in the simulations in the EDA software.The phase sequences are determined by the signals from detecting the current of each phase.The method is not only suitable for controlled rectifier circuit,but also for PWM rectifier circuit and active inv... |
