Evaluation and Design of a Three - Phase Inverter for a Maglev Application

This paper examines an early, proof of concept solution for the design of a three - phase power inverter. The need for an inverter design is required for the drivetrain component (Linear Induction Motor) of a magnetic levitation / Hyperloop transportation system. The design revolves around a typical inverter topology driven by an open-loop controller design. The design proposed in this paper is the integration of an Arduino microcontroller and an inverter circuit. The proposed inverter circuit consists of the main components which includes a three - phase gate driver and Insulated Bipolar Transistors (IGBTs) rated for 600V and a PWM controller. The controller used provides the required pulse width modulation (PWM) signals to drive the inverter circuit. The validity of the proposed design is proven through the comparison of the simulations performed in PSIM and the experimental results.
