Influence of hazardous EM fields on large objects
 Klučka, Jaroslav ; Kovács, Peter (referee) ; Řezníček, Zdeněk (advisor)
This bachelor thesis deals with simulation of influences of electromagnetic field on an aircraft via computer program PAM-CEM. The aim of the simulation is verification of conditions for placing equipment and cables in chosen places. There were chosen two outer interfering electromagnetic fields: High Intensity Radiated Fields HIRF and a lightning bolt. During the simulation of HIRF, the plane was radiated by outer electromagnetic field. The decomposition of inner electromagnetic field was monitored during the exposure. Then, the electrical intensity was measured in three places, where the location of susceptible electronical devices was predicted. During the simulation of lightning bolt only indirect effects were taken into consideration. Current impulse was implemented into the skin of the aircraft and the decomposition of surface current was monitored.

Control of Parallel Active Filter by Using dSpace 1103A
 Paclt, Zdeněk ; Šimek, Petr ; Valouch, Viktor
This work shows that nonlinear control technique of a shunt active filter is well suited to compensate for characteristic current harmonics that are generated by nonlinear loads. The proposed control is based on two inner current loops and an outer dc bus voltage regulator loop. There is no interaction between inner and outer loops in addition to good performance in both steady-state and transient operation. Active filters represent a modern and effective resource for suppresing interfering phenomena in the electrical supply.
