Noise, Vibration and Electromagnetic eFFects Generated by Semiconductor Converters in Traction Vehicles
Budek, P. ; Chmelíček, M. ; Jehlička, Vladimír
New problems emerge in the vehicles of city mass transportation due to application of new power switching devices and their control circuitry. Measurements were performed in a low-floor trolleybus ŠKODA 21Tr equipped with power converters based on GTOs and IGBTs. They were aimed at finding the sources of noise and vibrations in the passenger space, at verifying their influence and finding methods for their limitation. Similarly, The same attention was paid to the problems of electromagnetic interference.
