Abstract
Abstract A system and method for developing a cost efficient electronic power supply system that handles a range of supported electronic circuits is provided. The electronic power supply system adaptively configures the power applied to electronic circuits. Thereby, eliminating redesign of a power supply system when a newly developed or different electronic circuit is implemented. When an electronic circuit is attached to the electronic power supply, a controller confirms electronic circuit presence and queries for electronic circuit power on requirements. As more electronic circuits are added, the controller examines each electronic circuit power on requirements and determines if a power conflict is present. If a conflict exists, the controller will not supply power to the electronic circuits until the conflict is resolved. If a conflict does not exist, the controller powers up the present electronic circuits according to desired power on requirements by broadcasting commands to power supplies, some of which are programmable.
