초록

An UPS must be synchronized in frequency and phase relationship with the mains power supply. This paper describes and tests a digital phase-locked loop(DPLL) circuit of the open-loop method designed by full software with TMS320c31 digital signal processor. finally, the performance of the proposed DPLL is shown and discussed through simulation and experiment.
