Adaptive control of electrical devices to achieve desired power use characteristics

摘要

A system and method is provided for energizing and managing digitally-controlled devices at different levels of granularity, to achieve desired power use characteristics. At the lowest level, a digitally-controlled device is energized using a variable load-sensing adaptive control (VLSAC). Operation of the device is controlled using digital signals input to the device, so that limits on parameters, such as power consumption are met. A plurality of VLSACs can be coupled to a power distribution unit (PDU), which is controlled to achieve desired levels for selected parameters, set for the PDU. Multiple PDUs can be coupled to a power conversion and regulation unit (PCRU), which can be controlled by a master control to achieve a desired power profile for an entire facility, enabling the facility to meet requirements of a utility supplying the power and thus, reducing operational costs. The VLSACs and PCRU include high efficiency power sources having low distortion.

1. A power supply and control module (PSCM) configured to provide regulated AC and DC power to a digitally controlled load, the power supply and control module comprising:
a variable load-sensing adaptive controller (VLSAC) configured to accept an alternating current (AC) input and provide one or more regulated direct current (DC) voltages to the digitally controlled load; wherein the VLSAC is configured to provide digital load commands to the digitally controlled load, and wherein the digitally controlled load is configured to change its electrical load characteristics in response to the digital load commands; wherein the VLSAC is configured to receive digital load information from the digitally controlled load; and wherein the digital load information is used as a control input for control of the digitally controlled load.
