A DSP TMS320LF2407 BASED IMPLEMENTATION OF PWM FOR SINGLE-PHASE AC-DC BIPOLAR CONVERTER WITH A UNITY POWER FACTOR

摘要

This paper deals with the study and the implementation of a D.S.P (TMS320LF2407) controlled single-phase AC/DC converter using PWM strategy, including sinusoidal triangular strategy (SPWM). After the description of its functioning principles, its modeling and the converter control system, we have analyzed the modeling parameters influence on the converter behavior using that strategy. The study was led by simulation and validated experimentally on testing ground with a DSP designed and built in the laboratory.
