    Abstract: According to one embodiment, a power supply device connected to a power grid is provided. The power supply device includes an inverter, a control unit configured to control operation of the inverter using a first parameter value so as to simulate characteristics of a synchronous generator, and an acquisition unit configured to obtain a second parameter value different from the first parameter value. The control unit is configured to control the operation of the inverter by changing the first parameter value to the acquired second parameter value.

    Abstract: A transformer between waveguide and transmission-line includes a high-frequency circuit module, transmission-lines, a waveguide, and feed pins. The high-frequency circuit module has differential-pair terminals to input and output a differential signal. The transmission-lines are connected to the differential-pair terminals. The waveguide includes a first to third metal walls. The feed pins are connected to the transmission-lines inside of the waveguide. The feed pins have a first distance of approximately (λg/2) from each other. One of the feed pins has a second distance of approximately (λg*(1+2α)/4) from the third metal plane. “λg” is a wavelength in the waveguide and “α” is an integer which is equal or larger than “0”. Each of the feed pins has a third distance of approximately (a/2) from the first or second wall. “a” is length of the waveguide along the third metal wall.
