A Novel Two-Level Inverter Design for Efficient Energy Conversion in a Maglev Train Rail

Sammanfattning: This report covers the construction of a prototype inverter system designed to power the rail of a maglev train, from component selection through simulations and power demands to mounting and wiring the components into a cabinet. The inverter is made with insulated gate bipolar transistors controlled with pulse-width modulated signals provided by a custom microcontroller. The output of the inverter is a controllable three-phase square wave. The prototype was tested with a microcontroller designed for a different gate driver, making it necessary to design and create an adapter to be able to test it. The results showed that an inverter of two-level topology, together with capacitors, is a viable option for a 10 kHz switching frequency.
