Patent ID: 7795884

Claim:
A method performed by a computer for calculating the number of turns (t 1 , t 2 , . . . , t n ) per segment of a transformer coil winding which comprises n segments (S 1 , S 2 , . . . , S n ,) connected in series, the method comprising: assigning to each of said n segments (S 1 , S 2 , . . . , S n ) a predetermined value (R i ) representing the respective volts-per-turn value; assigning to each combination of segments (S 1 -S n , S 1 -S n−1 -S n , S 1 -S 2 -S n−1 -S n , . . . ) obtained by the connection in series of one or more of said n segments with one reference segment (S n ) selected from said n segments a respective predetermined value (V 1 , V 2 , . . . , V n ) representing the voltage across each of said combinations; assigning a predetermined number of turns (t n ) to at least said reference segment (S n ); generating simultaneously a system of (n−1) linear equations in (n−1) unknowns wherein said (n−1) unknowns represent the number of turns for all segments other than said reference segment (S n ); solving said system of (n−1) linear equations simultaneously to thereby determine the number of turns of all segments other than said reference segment (S n ).
