Patent ID: 7502699

Claim:
A system, comprising: a metered front end rectifier system, further comprising: an alternating current to direct current (AC/DC) rectifier coupled to an AC power source that converts received AC power to DC power at a rectified DC voltage; a modular direct current to direct current (DC/DC) conversion unit coupled to the AC/DC rectifier and to an intermediate DC voltage bus that converts power received at the rectified DC voltage to an intermediate DC voltage; and a meter circuit configured to meter power flowing from the AC power source to the AC/DC rectifier, the meter circuit having a coupling circuit, a transducer, a counter circuit and a memory, the coupling circuit being electromagnetically coupled to the power flowing from the AC power source and being operative to generate an AC analog signal corresponding to at least one of current and voltage of the power flowing, the transducer being operative to convert the AC analog signal into a digitized pulse signal, the counter circuit being operative to count a number of pulses of the digitized pulse signal during a predefined time interval, the memory being operative to store information corresponding to the number of pulses counted during the predefined time interval; a memory system that stores information pertaining to the operation of the system; at least one processing system coupled to the memory system, wherein the processing system accesses the memory system using a modifiable memory access control algorithm which controls memory access functions; and a power controller unit coupled to the processing system and the metered front end rectifier system, wherein the information corresponding to the metered power is communicated to the power controller unit from the metered front end rectifier system, and wherein the power controller unit adjusts operation of the processing system based upon the received metered power information to either increase power use or decrease power use based upon a predefined value of consumed power.
