  • Publication number: 20250047618
    Abstract: A relay device relays communication. The relay device includes: a receiving unit that receives communication data from a communication device; a storage unit that stores the communication data received by the receiving unit; and a processing unit that performs processing. A first period and a second period are alternately set. The processing unit changes the total number of the first periods and the second periods included in a next predetermined period each time a predetermined period including the first periods and the second periods passes. The processing unit determines whether or not the communication data is stored in the storage unit. When it is determined that the communication data is stored in the storage unit, the processing unit specifies a period to which a communication determination time at which the determination has been performed belongs, from the first period and the second period.

  • Publication number: 20250030345
    Abstract: The power conversion device can undergo autonomous search control for ZVS without a larger circuit area or lower reliability. The power conversion device performs, in each switching cycle, an operation of turning the control switch (CTLSW) on and afterward off while the synchronous rectification switch (SRSW) is off, and then turning the synchronous rectification switch on and afterward off while the control switch is off. Whether the inductor current (iL) is positive or negative is detected at the detection timing backed by a predetermined period (Text) from a timing at which the synchronous rectification switch switches from on to off, based on the detection result, the on-period (TOFF) of the synchronous rectification switch is corrected.
