Title:
POWER SUPPLY EQUIPMENT AND CONTROL METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2775536
Kind Code:
B2
Abstract:

PURPOSE: To enhance reliability without enlarging a power supply section by recognizing the operating state of other power supply control section at the time of resetting and matching the operating state so that the designating state for the power supply section will be identical.
CONSTITUTION: Each power supply control section 11 normally writes the operating state of its power supply control section 11 into a counterpart notification register 16 thus notifying the operating condition to other power supply control sections 11. At the time of resetting, operating state of other power supply control section 11 is read out from the notification register 16 and recognized. The operating states are then matched so that the designating states for the power supply section 13 will be identical at each power supply control section 11, and any one of the power supply control sections 11 delivers an operation command to the power supply section 13 through an OR circuit device 14. Consequently, the power supply section can feed power through a minimum necessary constitution.
