Development of Space Vector Pulse Width Modulation Rectifier Test Platform

This thesis is based on the development of high-power special frequency transformer. The software algorithm of high power rectifier is studied. The voltage space vector pulse width modulation (SVPWM) control mode is determined to achieve the rectifier. In this thesis, the rectifier test platform is designed. From the point of view of software, the double loop control strategy, three-phase software phase-locked loop (PLL), decoupling control and start-up impulse suppression and other key technologies are studied and solutions are proposed. Using CCS5.1 software programming platform, the rectifier control program and control algorithm are designed and verified. Finally, the hardware test platform is built, and the debugging test is carried out to verify the correctness of the software control program. SVPWM rectifier has achieved the expected technical specifications.
