Abstract
Global warming is a big issue which we are trying to combat. The main contributor to this problem is the increased CO2 emission in past centuries. Electric busses are able to provide this as they would not emit any greenhouse gasses directly. The problem is that instead of carbon-based fuels it would make use of a battery to power the motor. Batteries yield less energy in comparison to conventional carbon-based fuels which would reduce the driving range for the bus. To allow a longer driving range the so-called “opportunity charging” could be implemented. The problem is that “opportunity charging” is currently done through metal contacts which could wear down fast due to weather effects. Inductive Power Transfer presents a promising solution for opportunity charging of electric buses. This results in no mechanical contact between the charger and the vehicle and less maintenance than the current chargers. This thesis explores the optimal modular design and converter topologies to address key challenges in efficiency optimization, high-voltage stresses, inter- and cross-coupling and implementation of quasi-two level neutral-point-clamped converters....
