 12 Aug 2008 20:04 Inductive coupling power transfer |

Inductive power transfer can mean a lot, from 50/60 Hz mains frequency up to MHz, with different distances to span.
It's sometimes used for household appliances as electric toothbrush or shavers. For low and medium frequencies, it can be calculated from basic electromagnetic relations and simulated by simple 2D simulators as Quickfield. Self and mutual inductance of the coupler coils are almost completely describing the system.
