Embodiment Construction

[0025] [Summary of Examples]

[0026] The summary of the embodiments of the present invention includes at least the following content.

[0027] (1) A distributed constant type transformer is provided between an AC power source having a frequency f and a load having a resistance value R, and includes: a first converter connected to the AC power source and having a length of λ / 4; and The second converter is arranged between the terminal and the load of the first converter and has a length of λ / 4, where the wavelength at the frequency f is λ.

[0028] In the above transformer, the impedance of the first transformer is Z c1 And the impedance of the second converter is Z c2 In the case of input impedance Z in It is shown below.

[0029] Z in =(Z c1 2 / Z c2 2 )·R=k·R

[0030] Here, k is a constant. Input impedance Z in It is proportional to the resistance value R of the load. Therefore, regardless of the resistance of the load, an output voltage proportional to the input voltage can be ...

Abstract

Provided is a transformer, which is a distributed constant transformer provided between an AC power source having a frequency (f) and a load having a resistance (R), comprising, with a wavelength of λ for the frequency (f): a first transformer connected to the AC power source and having a length of λ / 4; and a second transformer provided between the end of the first transformer and the load and having a length of λ / 4. Such a transformer is small and lightweight, and does not need a coil, a core, or the like as in a conventional transformer.

Description

Technical field [0001] The invention relates to a transformer. Background technique [0002] In commercial AC power transmission and distribution systems, transformers are used. Just near the consumer's house, a pole transformer is used, which converts, for example, 6600V (50Hz or 60Hz) into 200V (see Non-Patent Document 1). Such a pole transformer has a thick coil as a wire wound around an iron core, and therefore has a considerable weight. For example, a pole transformer with a diameter of 40 cm and a height of 80 cm has a weight of approximately 200 kg, including insulating oil and a casing. [0003] On the other hand, in order to realize a smart grid as a next-generation power system, SST (Solid State Transformer) is being studied. For SST, a high-frequency transformer is used (for example, see Non-Patent Document 2).
