  The number of OA devices, home electrical appliances and the electronic equipment is enormous in the big city. Furthermore, a lot of devices are used which exclude harmonics regulations. Most of these have low power factors. When the quantity of devices increases, electricity transmission efficiency decreases. Further side-effects include an increased distortion in the electric current in power lines, such as in indoor wiring, and an increase in electromagnetic noise. In addition, this is a cause for other devices to malfunction. We propose that the living environment is degraded due to the prevalence of OA devices in the big city.
  We have developed a cheap, small-scale power factor improvement device. This device is compatible with general home electrical appliances and small electronic equipment. As a result, it possible to clean indoor electricity and save energy.
