See full text

A transformer of distributed-constant type is provided between an AC power supply with a frequency f and a load with a resistance value R, and includes: a first converter connected to the AC power supply and having a length of λ/4; and a second converter provided between an end of the first converter and the load, and having a length of λ/4, where a wavelength at the frequency f is λ. Such a transformer has a small size and a light weight, and does not need a coil, an iron core, and the like as used in a conventional transformer.
