Title: Feeding method for electronic equipment
Inventor: MIYAMOTO MITSUO
IPC: G06F1/00
Filed: 1987-11-02
Abstract: PURPOSE:To keep the stable working of an electronic equipment by feeding a logical unit with the minimum voltage displacement. CONSTITUTION:A power unit 5 of a large current is set near a logical unit 3 together with power units 6-8 of comparatively small currents set further away from the unit 3 respectively as long as the section areas of bus bars 9, 10, 15 and 17 are constant. In case these bus bars have different section areas, the length of a feeding bus bar is decreased in response to the capacities of those power units and the section area of bars 9-17. Thus the voltage drop due to the electrical resistances of bars 9-17 is minimized. As a result, the potential difference of the unit 3 is reduced and the stable working is secured for the unit 3.
