Systems and Methods to Increase the Reliability and the Service Life Time of Photovoltaic (PV) Modul
Publication number: 20230421096Abstract: An apparatus may determine a parameter related to a voltage value at a midpoint terminal of a system power device, and may adjust a voltage applied to a second terminal of the system power device based on the parameter and a reference value. The second terminal may be different from the midpoint terminal.Type: ApplicationFiled: September 11, 2023Publication date: December 28, 2023Inventors: Ilan Yoscovich, Liron Har-Shai, Amir Grossberg, Matan Atias -
Publication number: 20230396070Abstract: A method may include: applying a first voltage on at least one first terminal of a first direct current (DC) bus electrically connected to a power source, obtaining at least one indication that discharge of a second voltage related to the first voltage should be performed, and discharging the second voltage by electrically connecting at least one second terminal of a second DC bus to a ground in response to the at least one indication. Another method may include: injecting a current at at least one terminal of a direct current (DC) bus that is electrically connected to a power source, simultaneous to injecting the current, measuring an insulation relative to ground, obtaining an electrical parameter related to the power source, and, in response to the electrical parameter, maintaining the current injected at the terminal of the DC bus without ceasing the measuring of the insulation relative to a ground.Type: ApplicationFiled: August 17, 2023Publication date: December 7, 2023Inventors: Ilan Yoscovich, Liron Har-Shai, Amir Grossberg, Matan Atias, Daniel Zmood, David Avraham

Publication number: 20230387778Abstract: Systems, apparatuses, and methods are described for power conversion. In some examples, the power conversion may be done by an inverter configured to convert a direct current (DC) input to an alternating current (AC) output. The inverter may include a plurality of capacitors connected at the input of a DC/AC module. The system may include a housing configured to house the inverter. Voltage control circuitry may be configured to increase a voltage at the input of the DC/AC module inside the housing of the inverter.Type: ApplicationFiled: August 15, 2023Publication date: November 30, 2023Inventors: Matan Atias, Liron Har-Shai

Publication number: 20230231389Abstract: A power system may comprise a power system controller and a power storage. The power system controller may comprise a first pair of power terminals, a second pair of power terminals, at least one switch, and a central controller coupled to the at least one switch. The power storage may comprise storage power terminals connected to the first pair of power terminals. The second pair of power terminals may be coupled to a power source. The power system controller may be configured to control the switch to connect and disconnect the second pair of power terminals. The power system controller may be configured to receive power from the power storage during a process of connecting and disconnecting the second pair of power terminals.Type: ApplicationFiled: January 13, 2023Publication date: July 20, 2023Inventors: Matan Atias, Ziv Moscona, Ran Zorea, Liron Har-Shai

Publication number: 20220319789Abstract: A relay array may connect an electrical device (e.g., an inverter, power converter, etc.) to a utility grid. Based on a detection of a power interruption or fault, the relay array may disconnect the electrical device from the grid to ensure safety or reduce damage to the electrical device or grid. The relay array may include one or more electromechanical relays (e.g., latching relays). A safety catch may prevent the latching relay(s) from changing states. The electrical device may be configured to facilitate removal of the safety catch once the ability to change states is desired. The latching relay(s) may also be supplied with a power pulse for changing a state of the latching relay(s). The power pulse may be provided by a power bank that may be maintained with power in case of a power interruption or fault.Type: ApplicationFiled: April 26, 2022Publication date: October 6, 2022Inventors: Amir Grossberg, Yoav Berger, Reuven Savitzky, Dor Shoshani, Elad Toraty, Liron Har-Shai, Matan Atias
