Autonomous power supply with higher EMC requirements
 Burian, Jan ; Deneš, Roman (referee) ; Hejátková, Edita (advisor)
This paper deals with design of mechanical and electrical components of autonomous power supply and its testing. It consists of selecting of the materials, draft of shapes and calculations of feed-throughs for the source container to ensure the required electromagnetic characteristics. It also includes the selection of electronic components, comparison of DC-DC converters and filter design with focus on the highest electromagnetic immunity and the lowest electromagnetic emissions.

Electromagnetic emissions of a trolley-bus with IGCT-based drive
 Doležel, Ivo ; Jehlička, Vladimír ; Škramlík, Jiří ; Valouch, Viktor
The paper describes utilisation of a new IGCT-based element in DC inverter designed for feeding of a DC traction motor for trolley-bus. It deals with emissions of electromagnetic field (EMI) produced by operation of the inverter EMI was measured and calculated on a simplified model. Realised was a preliminary best during a low-speed trip within frequency range 150 kHz - 30 MHz. The results exhibit a good accordance with European Standards EN 50121-2, EN 50121-3-1.
