    Publication number: 20240075841
    Abstract: Described are a method for suppressing overshoot of an output voltage or output current, a charging device, and a medium. The method for suppressing the overshoot of the output voltage or output current includes the following. A loop in an open-loop state in a closed-loop control circuit is determined. A wave-sending control value output by the closed-loop control circuit at a present beat is obtained. The wave-sending control value output at the present beat is assigned to an open-loop output value at the present beat, where the open-loop output value is an output value of the loop in the open-loop state. An open-loop output value of a loop in the open-loop state at a next beat is calculated by using an assigned open-loop output value at the present beat.

  • EHT station configured to encode U-SIG for transmission of EHT PPDU of 40, 80, 160 and 320 MHz bandwidths
    Patent number: 11924866
    Abstract: Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).
