Abstract :
A design of an inductive power and data transfer for multiple stationary loads is presented, which focuses on stable load voltages and robust communication. Loads are contactless charging units of electric vehicles at car parks, or adjustable speed drives as used in factory automation and intra-logistics. A lumped parameter model is deduced for system studies. Parameters of the inductive couplers are taken from FEM calculations. An inductive data transfer for stable and robust communication is added. The design principles are verified at laboratory scale with a purpose built test stand.
