  • Patent number: 11183839
    Abstract: Disclosed examples relate to a power conversion system configured to provide a power output from an arrangement of direct current (DC) power sources. One example power conversion system includes multiple power sources PV(n), n=1 to x, connected in a series. For each power source PV(n) for n=1 to x?1, the power conversion system includes an intermediate bidirectional voltage converter VC(n) connected to a first terminal of the power source PV(n), a first terminal of power source PV(x), and a second terminal of power source PV(1). Each intermediate bidirectional voltage converter VC(n) includes a first switch operable in a pulsed mode to boost a power output by power source PV(n) and a second switch operable in a pulsed mode to reduce a power output by power source PV(n). The power conversion system also includes a balancer VC(x) connected to the first terminal of PV(x) and to a load.

  • Patent number: 11131538
    Abstract: The present disclosure relates to identifying azimuth error and determining an azimuth of an antenna installed in a cell of a cellular network. In a preferred embodiment, the network entity receives a plurality of transmission parameters basis to which the network entity identifies a target cell. The network entity further divides angular region of the cell serving the target cell into a plurality of cones out of which a target cone is identified by the network entity. The network entity then performs first iteration yielding a first azimuth, and in an event of an azimuth error in the first azimuth, the network entity performs second iteration yielding a second azimuth. The present disclosure also encompasses predicting an optimum azimuth of said antenna in an event of azimuth error/s in the first azimuth and the second azimuth.

  • Publication number: 20210126471
    Abstract: Systems and methods are provided for maintaining charge control of a battery array where a plurality of batteries is serially connected. Each of the battery has an odd switch and an even switch. A battery charge current and voltage for each of the battery is controlled by establishing a controlled charging for the batteries. The odd switch is controlled using a Pulse Width Modulation (PWM) signal. An inductor coupled with the battery array supplies stored power to each of the battery of the plurality of batteries. The battery charge current and voltage is managed by either establishing a restricted battery charge current or battery voltage for one of the battery with high SOC or the battery that is to be charged with lower current rate is switched by a lower duty cycle PWM signal while the remaining batteries are charged with a higher duty cycle PWM signal.
