Three Phase VSI Control System Rapid Prototyping with TI C2000 MCU and PLECS Coder

Abstract

This paper presents the rapid prototyping and validation of a Three-Phase Silicon Carbide (SiC) Voltage Source Inverter (VSI) in open-loop control and closed-loop control in TI C2000 microcontroller using PLECS coder real-time control tool. Comparative studies are also conducted to study the crucial factors that impacts the performance of the inverter. In open loop control, the experiment on the effect of using different PWM control strategies in terms of changing the modulation index was investigated. While in closed loop, the verification of the feedback of the PI control were studied to ensure that the output was able to maintain at the desired output level. The simulation results are compared with the hardware measurement results to validate the open and closed loop operations of the inverter. The 3-phase voltage source inverter rapid prototyping hardware platform developed is applicable for university lab teaching and advanced inverter control feature development.
