System for contactless transmission of power and data, has windings, which are designed such that total voltage from two power coils is not induced to communication coils

摘要

The contactless power and data transmission system has a mobile part arranged in a movable manner relative to a system part. The system part has a power coil (L1) and a communication coil (K1), where the mobile part has another power coil (L2) and another communication coil (K2). Each power coil has two windings, and each of two communication coils has two windings, where winding axes of the windings are aligned in a parallel manner. The windings are designed such that total voltage from the two power coils is not induced to the communication coils.
