Document Type and Number:
WIPO Patent Application WO/2015/029744
Kind Code:
Provided is a transformer device provided between a power source and a load with a resistance value R, wherein, where n is a natural number of at least 4, provided is a two terminal pair circuit configured by mutually connecting n reactance elements, and with respect to a discretionary resistance value R of the load, a real number component of an input impedance Zin of the two terminal pair circuit is represented by k·R, where k is a constant, and an imaginary component is 0. This manner of transformer device is small and light, and does not require the coil, iron core or the like of conventional transformers.
