EMI Generated by Trolley-Bus with IGCT-Based Drive
Budek, P. ; Doležel, Ivo ; Jehlička, Vladimír ; Škramlík, Jiří ; Valouch, Viktor
The paper describes the employment of a new IGCT element in a dc chopper designed for feeding a dc trolley-bus traction motor. The discussed radiated EMI noise generated during the chopper operation was measured and calculated on a simplified model. The preliminary slow moving tests within the range 150 kHz - 30 MHz were performed. The results of the measurements of magnetic field exhibit the compliance with the European Standards EN 50121-2, EN 50121-3-1.

Modern Switching Devices Will Improve Electric Vehicles in City Mass Transportation
Bartoš, Stanislav
First, the lecture outlines the prospective trends in city mass transportation. In further sections, principles of electric traction drives are discussed. As the lecture is intended for broad technical audience not specialized in power electronics, only the most elementary principles of converters are explained. Their improvement is based on the employment of IGBTs and IGCTs, which are the state-of-the-art semiconductor power switching devices.
