Designing the U/F Control Circuit and Space Vector Modulation for Three-Phase Inverter based on DSPIC30F4011

Abstract

Three-phase inverters using space vector modulation (SVPWM) are among the most popular inverter architectures available today. The inverter design and manufacturing process usually goes through simulation, hardware design, and programming on the microcontroller and calibration. The paper presents the construction and fabrication of the force circuit and control circuit that implements the SVPWM spatial vector modulation algorithm and implements the U/F speed control method on the microcontroller for the inverter in a way detail. U/F control and SVPWM spatial vector modulation algorithm are tested on dsPIC30F4011 microcontroller and a small power inverter model to illustrate implementation and execution.
