Abstract :
This paper presents a method of three-phase power-frequency signal source based on pulse transform technique. A digital logical circuit is designed to produce pulse signal, then the pulse signal is transformed to quantitative setup the frequency, amplitude and phase of the three-phase signal source. A CPLD chip is used in the digital system to set the frequency, phase and amplitude of the three-phase power-frequency signal. This method does not need waveform memory and DAC, with the advantage of operating simply, low cast of hardware, and wide application.
