  • Patent number: 11289905
    Abstract: Disclosed in the present invention is a voltage and current control method for a direct-current transmission system. The method comprises: calculating a DC voltage reference value of a voltage source converter of a DC voltage control end, on the basis whether a direct-current voltage end of a direct-current pole of a direct-current transmission system substantially controls a direct-current voltage; using ½ of the calculated direct-current voltage reference value of the voltage source converter as a bridge arm voltage direct-current bias, calculating a difference between the direct-current voltage reference value of the voltage source converter and a measured direct-current voltage value, and inputting the difference into a direct-current voltage control outer loop of the voltage source converter to perform closed-loop control, so as to control the direct-current voltage or the direct current of the direct-current pole.

  • Patent number: 11288146
    Abstract: A method for recovering a clock signal from a data signal by using a clock recovery module is described. Edge timings of the data signal are accumulated. The edge timings accumulated are transformed into one reference bit period. A time offset for the reference bit period is determined. A reference clock signal is determined based on the time offset. The number of bits within a system clock of the clock recovery module is determined. The clock signal is recovered based on the reference clock signal and the number of bits. Further, a clock recovery module as well as a computer program are described.

  • Patent number: 11281282
    Abstract: Technologies exist that allow for power to be supplied over a data connection, e.g., Power over Ethernet (PoE). Power sourcing equipment (PSE) supplies power to a powered device (PD) over the data connection. There may be applications in which it is desired or necessary to insert an intermediary device on a data connection between the PSE and the PD. An intermediary device is disclosed that can be inserted between a PSE and a PD. The intermediary device attempts to power itself using power supplied by the PSE over the data connection, rather than using an auxiliary power supply. In some embodiments, the intermediary device acts like a PD and requests from the PSE enough power for both itself and the actual PD. The intermediary device then also acts as a PSE to deliver unused power over the data connection to the actual PD.

  • Patent number: 11281283
    Abstract: The Control Layer IO System (“CLIOS”) software is an energy management system taking into account the performance requirements of the target software and the properties and limitations of the target hardware to optimize energy use of a programmable electronic device. CLIOS is generated in a one-time process and once generated is loaded onto the target. CLIOS is complementing or replacing the power management infrastructure of the main operating system. CLIOS comprises three main components: the CLIOS daemon that operates in the user space; the CLIOS driver that operates in the kernel of the main operating system; and the CLIOS kernel, which can run on an auxiliary core if present in the system. CLIOS can be structured to take advantage of various architectural features of a system, ranging from simple single-core designs to heterogeneous, multi-core systems comprising one or more low power auxiliary cores.

  • Patent number: 11283289
    Abstract: An uninterruptible power supply (UPS) system with stranded power recovery has a plurality of UPS modules with one or more of the UPS modules usable to provide stranded power to a recovered power bus. When a UPS module is used to provide stranded power to the recovered power bus, the AC/AC converter associated with that UPS module provides AC power that is synchronized with AC power being provided to the recovered power bus by each of the other AC/AC converters that are providing AC power. In this manner all of the AC/AC converters that are providing AC power to the recovered power bus have the same voltage, the same frequency and are in phase.
