| Abstract: | It is important to obtain phase of source voltage accurately in a design of power electronic equipments. The principles of three-phase Software Phase-Locked Loop（SPLL） based on DzQ transformation are studied deeply in this paper, and its realization method based on DSP28335 is illustrated, then a digital software three-phase PLL based on DSP28335 is proposed and applied into PWM rectifier system. Finally, simulation and ~xperiment results verify the validity and feasibility of SPLL based on DSP28335 proposed in this paper. And practical application shows the superiority performance of software PLL and DSP28335. |
