High-density, Multilevel Inverters for Aerospace Applications
Christopher Barth
Department of Electrical and Computer Engineering
University of Illinois at Urbana-Champaign
High specific power density electric machines typically employ non-metallic materials instead of iron, which
consequently decreases the machine’s winding inductance. Since the low reactance windings cannot
effectively filter PWM voltage waveforms, we propose a flying capacitor multilevel (FCML) inverter strategy
with high effective switching frequency to generate a high quality sinusoidal waveform without large
external inductance.
This presentation will discuss the work which has been done in the design of a multilevel inverter for use in
a 200 kW motor drive application. Design considerations and the current status of the hardware prototype
will be discussed as well as some of the practical implementation challenges which have been addressed.
Modeling, Simulation and Prototyping Of An
Electromechanical 72 Kv Switch
Martin Lopez-Guerra Belzunce and Marcos Javier Yusta
Department of Electrical and Computer Engineering
University of Illinois at Urbana-Champaign
Modeling and simulation of an electromechanical switch for a company product design, analyze its
performance and document the results. The idea is to design a smaller, lighter, high voltage solid
dielectric circuit breaker, using the best design practices from medium voltage. This project focuses on
designing and prototyping the magnetic actuator and the power electronics in order to make the 72kV
circuit breaker/recloser solid dielectric design possible.
