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.
