This paper analyzed the electromagnetic disturbances in the driving system of a fuel cell bus. First, the distribution of the disturbance source in the driving system surveyed by measurement was introduced. Then, the characteristics of the conductive emission were presented. Based on the multiconductor transmission line model, the paper analyzed the electromagnetic conductive interference in the driving...
This paper analyzed the distribution and the characteristic of the disturbances in the driving system of a fuel cell bus by measuring both the conductive and radiative emission. Statistical method was used to investigate the parameters of the typical voltage waveforms, which were compared with the standard ones in IS07637-2. The results are useful for the farther investigation of the EMC problems...
Hybrid electric Bus has serious EMC problems. Normal distribution is proved suitable to describe the noise fluctuation on input port of inverter. Typical noise patterns are summarized with seven key parameters. Then crosstalk between power cables and nearby signal cables is analyzed with injection of these typical noises. Time parameters of noises are observed can influence the crosstalk significantly...
Based on the multiconductor transmission line model, this paper analyzed the electromagnetic conductive interference in the driving system of fuel cell bus by calculation. Firstly, the propagation characteristics of the conductive interference in the cable were analyzed. Then, the common mode current and its coupling effect were investigated. Finally, the coupling between the driving system and the...
Fuel cell vehicle would cause serious EMC (electromagnetic compatibility) problems. Now the related EMC research is being focused on. Up to now, there still have been no expert EMC standards on it. So it is necessary to realize the characteristics of the disturbance source on the new type of fuel cell vehicle. This paper applied statistical methods to analyze the conducted disturbance sources on fuel...
