Selective Connection Of Power Supplies

US Patent:

4812672, Mar 14, 1989

Filed:

Oct 1, 1987

Appl. No.:

7/103200

Inventors:

Michael L. Cowan - Cary NC
David C. Goodman - Durham NC

Assignee:

Northern Telecom Limited - Montreal

International Classification:

H02J 906

US Classification:

307 64

Abstract:

A circuit for selectively connecting or disconnecting one of two power supplies, connected in parallel, in the event of the failure of one of the power supplies. The mechanism used is a MOSFET inserted "backwards" in a control circuit such that when the MOSFET is turned "off" no current drain is permitted through the diode internal to the MOSFET. Such a method provides fast switching and may be employed in other circuits as a replacement for relays.
