Wireless power transfer

Leading manufacturing technologies for wireless power transfer systems

Wireless power transfer overview

Inductive power transfer

The principle of inductive power transfer is based on alternating electromagnetic fields. A transmitter coil generates a magnetic field which induces an alternating voltage in the receiver coil. This voltage is rectified and is available on the vehicle side.

IPT system architecture

An inductive power transfer system consists of a primary side (transmitter) and a secondary side (receiver). In both parts, the transmitter or receiver coil is the central component for magnetic coupling between the system groups.
