| Abstract |
Contactless inductive energy transmission over a large air gap becomes more and more attractive for
different applications. The paper investigates the influence of geometrical and electrical parameters on
energy transmission of different contactless magnetic assemblies with air gaps of several centimetres.
The investigations are carried out by means of flux simulation and measurements. Especially the
dimensions of the primary and secondary system, the air gap lenght and the number of turns determine
the transmission behaviour. The efficiency of contactless energy transmission systems is mainly
influenced by the transmission frequency. In particular the efficiency of systems with a large air gap can
be considerably improved by using higher transmission frequencies in the range of approximately
100 kHz. Therefore, a high frequency phase-shifted controlled IGBT-inverter is developed. |
