Abstract
Most mains-operated equipment in use today is connected to the
supply via plugs and sockets. These are generally acceptable in benign
environments, but can be unsafe or have limited life in the presence of
moisture. In explosive atmospheres and in undersea applications, special
connectors must be used. This paper describes a technique, the
contactless energy transfer system (CETS), by which electrical energy
may be transmitted, without electrical connection or physical contact,
through nonmagnetic media of low conductivity. The CETS, which has been
used to transfer up to 5 kW across a 10 mm gap, employs high-frequency
magnetic coupling and enables plug-in power connections to be made in
wet or hazardous environmental conditions without the risk of electric
shock, short circuiting, or sparking. Energy may be transmitted without
the necessity for accurately manufactured “plug-and-socket”
mechanisms and may be transmitted from source to load, even when there
is relative motion. Load-source voltage matching may be made inherent to
the system
