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
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.
