Abstract Details

2023, Master of Science in Engineering, Youngstown State University, Department of Electrical and Computer Engineering.
The surging electric vehicle (EV) industry is driving a growing demand for high-performance motor drives as the motor drive systems play a crucial role in an EV’s performance and efficiency. Choice of techniques for DC-AC conversion is instrumental in the performance of Voltage Source Inverters (VSI). In this study, a Field Programmable Gate Array (FPGA)-based PWM (Pulse Width Modulation) architecture is proposed for a VSI topology. A variable frequency and soft-starting PWM architecture is proposed for a three-phase induction motor drive. The proposed architecture allows the implementation of Sinusoidal PWM (SPWM) and Space vector PWM (SVPWM) for the control of a three-phase induction motor (TPIM). In this thesis, line-current and phase-voltage characteristics of the TPIM are studied under diferent operating conditions. Simulink is used for the simulation and verifcation of the proposed architecture and experimental results are validated using four-pole squirrel cage TPIM. Harmonic contents for SPWM and SVPWM are studied and superiority of the SVPWM, which can be implemented using the same architecture, is established. Greater DC bus utilization and lower harmonics in SVPWM leads to better performance in terms of power conversion efficiency compared to SPWM. The proposed architecture utilizes a small fraction of the FPGA resources and can be easily integrated into a larger control system architecture. In addition, a PWM generator is designed for high frequency inverters used in wireless inductive power transfer (IPT) applications and is experimentally verifed.
