53412800, Aug 23, 1994

Filed:

Sep 27, 1991

Appl. No.:

7/767024

Inventors:

Deepakraj M. Divan - Madison WI
Keith W. Klontz - Sun Prairie WI
Donald W. Novotny - Madison WI
Robert D. Lorenz - Madison WI

Assignee:

Electric Power Research Institute - Palo Alto CA

International Classification:

H02M 5453
H02J 700

US Classification:

363 37

Abstract:

A contactless power transfer system, especially for powering electric loads, hazardous loads or underwater loads and the like. A converter supplies high frequency power to a conductor loop. A coupling sheath or link has a core-mounted conductor at least partially surrounded by a magnetic core which slidably receives a portion of the conductor loop within the link. An optional secondary converter converts power from the core-mounted conductor to meet the load requirements. A contactless power distribution system delivers power to a variety of loads through clamped-on or captive links attached at any location along the conductor loop. Methods are also provided of powering a movable electric load, or a stationary load from a movable source, and of distributing power to a plurality of portable electric loads.

H01F 4010
H02M 4504

US Classification:

320 2

Abstract:

A contactless recharging system and method for recharging an energy storage device onboard an electric vehicle has a primary converter for converting power from a power source into high frequency power. A secondary converter on board the vehicle is coupled to the battery for converting high frequency power into charging power supplied to the energy storage device. The primary and secondary converters are coupled together by a contactless coupling of a conductor loop and a coupling link forming a coaxial winding transformer. The coupling link has a magnetic core and a core-mounted conductor at least partially surrounded by the magnetic core. The core-mounted conductor selectively at least partially surrounds a portion of the conductor loop to transfer power therebetween. The core-mounted conductor is coupled to either the primary or the secondary converter, with the conductor loop being mounted to the other of the primary and the secondary converters.

International Classification:

H01M 1046
H01F 2700

US Classification:

320 2

Abstract:

A contactless recharging system and method for recharging a battery storage device onboard an electric vehicle has a primary converter station for converting power from a power source into high frequency power at a selected charging rate. The vehicle has a secondary converter for converting high frequency power into DC power to charge the battery. The converters are coupled together by a contactless coupling of a conductor loop and a coupling link forming a coaxial winding transformer. The coupled link and loop carry a communication indicating the selected charging rate of the battery. The link has a magnetic core and a core-mounted conductor at least partially surrounded by the core. The core-mounted conductor selectively at least partially surrounds a portion of the loop to transfer power therebetween. The core-mounted conductor is coupled to one of the converters, and the loop is coupled the other converter.

International Classification:

H02M 5293
H02J 700

US Classification:

363 37

Abstract:

A submersible contactless power transfer system, especially for powering underwater electric loads, including movable loads, such as underwater vehicles, elevators, or worksite equipment. A converter supplies high frequency power to a conductor loop. A coupling sheath or link has a core-mounted conductor at least partially surrounded by a magnetic core which slidably receives a portion of the conductor loop within the link. An optional secondary converter converts power from the core-mounted conductor to meet the load requirements. A contactless power distribution system is submersible to deliver power to underwater loads through clamped-on or captive links attached at any location along the conductor loop. Methods are also provided of powering loads submersed in water, including seawater, or other non-magnetic liquid mediums.

H02K 1/02

US Classification:

310 44, 310 68 B, 310 46

Abstract:

The present invention relates to an improved electric machine which, when operating in motor mode, produces rotational torque without using alternating magnetic polarity, but rather magnetic flux that utilizes coils arranged in a dipolar manner around an axial plane and independently removable stators.
