  • Publication number: 20240405429
    Abstract: An antenna element receives a first radio wave and outputs a transmission signal, and receives a second radio wave and outputs a reception signal. A phase conversion unit applies a predetermined phase shift amount to a signal to be input and then output the signal. A switch connects the antenna element to one of the phase conversion unit and external receiver. When the first radio wave enters the antenna, the switch connects the antenna element to the phase conversion unit, and the transmission signal to which the predetermined phase shift amount has been applied is radiated from the antenna element. A third radio wave radiated from each of a plurality of RIS elements is deflected in a predetermined direction. When the second radio wave enters the antenna, the switch connects the antenna element to the external receiver, and the external receiver receives the reception signal.

  • Publication number: 20240396426
    Abstract: A controller determines whether alternating-current power, output from a bidirectional AC/DC converter, is greater than or equal to a predetermined value, and whether the voltage value of a capacitor, detected by a first voltage sensor, is greater than or equal to a threshold value. The controller stops controlling the bidirectional DC/DC converter when determining that the alternating-current power, output from the bidirectional AC/DC converter, is not greater than or equal to the predetermined value and that the voltage value of the capacitor is greater than or equal to the threshold value. The controller charges the capacitor by controlling the bidirectional DC/DC converter when determining that the alternating-current power, output from the bidirectional AC/DC converter, is not greater than or equal to the predetermined value and that the voltage value of the capacitor is less than the threshold value.

  • Publication number: 20240380330
    Abstract: A control circuit performs at least one of a first phase shift control and a second phase shift control. The first phase shift control outputs a primary-side control signal so that a positive voltage is applied to a primary-side winding, and then outputs a secondary-side control signal so that a positive voltage is applied to a secondary-side winding when the voltage of the capacitor is higher than a battery voltage primary-side conversion value during activation of a bidirectional DC/DC. The second phase shift control outputs the secondary-side control signal so that a positive voltage is applied to the secondary-side winding, and then outputs the primary-side control signal so that a positive voltage is applied to the primary-side winding.
