Power distribution device and power distribution circuit

摘要

A power distribution device includes a number (N, N≧2) of power input terminals, a number (M, M≧2) of power output terminals, and a number (M) of power distribution circuits, each electrically coupled to a corresponding one of the power output terminals and electrically coupled to a number (P, P≧2) of the power input terminals. Each of the power distribution circuits includes a number (P) of diodes each electrically coupled between a respective one of the power input terminals and the corresponding one of the power output terminals, a switch element connected in parallel to one of the diodes, and a controller controlling the switch element to operate in a conducting state when the controller determines that power received at the power input terminal connected to the switch is normal, and controlling the switch element to operate in a non-conducting state when the power is abnormal.

1. A power distribution device comprising:
a number (N) of power output terminals each to be electrically coupled to a corresponding power supply; a number (M) of power output terminals each to be electrically coupled to a corresponding electronic device so as to output power thereto; and a number (M) of power distribution circuits, each electrically coupled to a corresponding one of said power output terminals and electrically coupled to a number (P) of said power input terminals; wherein each of the numbers N, M, and P is independently a positive integer not less than 2; wherein each of said power distribution circuits includes: a number (P) of first diodes each electrically coupled in a forward-bias arrangement between a respective one of said power input terminals and said corresponding one of said power output terminals; a switch element connected in parallel to one of said first diodes and electrically coupled to one of said power input terminals that is electrically coupled to said one of said first diodes; and a controller electrically coupled to said switch element and said one of said power input terminals that is electrically coupled to said switch element, said controller controlling said switch element to operate in a conducting state such that said one of said power input terminals that is electrically coupled to said switch element is electrically coupled to said corresponding one of said power output terminals through said switch element when said controller determines that power received at said one of said power input terminals that is electrically coupled to said switch element is normal, said controller controlling said switch element to operate in a non-conducting state when said controller determines that the power received at said one of said power input terminals that is electrically coupled to said switch element is abnormal.
