Patents by Inventor Tomomi MOCHIZUKI

Tomomi MOCHIZUKI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10468995
    Abstract: A power converter includes a rectifier that converts AC power from an AC power supply into DC power, a short circuit unit that short-circuits the AC power supply via a reactor, and a controller that controls the short circuit operation of the short circuit unit. The controller changes the number of the short circuit operation during a half cycle of an output waveform of the AC power supply on the basis of a load condition, and causes a delay time before short circuit from a zero crossing point of the output waveform of the AC power supply after changing the number of the short circuit operation to vary from a delay time before short circuit from a zero crossing point of the output waveform of the AC power supply before changing the number of the short circuit operation.
