Patent ID: 7545659

Claim:
An apparatus usable in power transformation system that can provide power from an AC source to an AC load, the apparatus comprising: a cycle counter for counting cycles representative of a frequency associated with power provided to an AC load; a first component capable of obtaining a first value from said cycle counter; said first value being indicative of a frequency error value indicative of a difference in frequency between the AC source and AC power provided to the AC load; a second component capable of receiving said first value and outputting a second value, said second value being indicative of whether to perform compensation of the AC power provided to the AC load based on a first threshold value and a second threshold value; a third component capable of initiating compensation actions when said second value indicates compensation should occur, wherein the compensation actions include adjusting a frequency of the AC power, a fourth component capable of scaling said first value; and a fifth component capable of determining a period of time over which compensation should occur.
