Study of DSP Comprehensive Experiment for Electrical Specialty Based on SVPWM and p-q Theory

Based on the two main theories in main circuit of three-phase power converter, namely pulse width modulation theory and instantaneous reactive power theory, comprehensive experiments of DSP TMS320F28335 are carried out aiming at senior students of electrical engineering major. During the experimental process, working principles of space vector pulse width modulation (SVPWM) and p-q theory are given, as well as the main hardware modules and key program codes used in DSP. The experimental teaching results show that the purposes of ability training such as students’ ability of better understanding, practical programming, experimental debugging and the weak-current combined with heavy-current training are obtained.
