Abstract:
1. A method of converting power from an input source for delivery to a load, where the load may vary over a normal operating range, comprising: providing an integrated adaptive array having an input, an output, a number, N, of input cells each having a respective number, P providing magnetic coupling between the turns to form a transformer common to each of the input and output cells; adaptively configuring the cells in and out of a series connection such that the turns of selected ones of the input cells are adaptively connected in series and the turns of selected ones of the output cells are adaptively connected in series to provide an adaptively adjustable transformer turns ratio, which is a function of the ratio of (a) the sum of the number of turns in the selected ones of the series-connected output cells to (b) the sum of the number of turns in the selected ones of the series-connected input cells.
