  • Patent number: 10819098
    Abstract: A method for detecting a voltage disturbance on an electrical line coupled to a utility that provides three-phase electrical AC power signals to a critical load that includes a transformer. The method includes reading instantaneous voltage measurements at a high sample rate of each of the three-phase power signals, and calculating a flux in the transformer at the sample rate for each of three-phase power signals by adding the instantaneous voltage measurements at the current sample point and at a previous sample point. The method includes calculating a flux error for each of the three-phase signals at the sample rate as a difference between the newly calculated flux and the oldest calculated flux. The method determines whether the flux error for any of the three-phase power signals is greater than a first predetermined percentage or less than a second predetermined percentage, and if so, identifies a voltage disturbance.

  • Patent number: 10797490
    Abstract: A battery charge system including an adapter node, a system node, a battery, a first isolation switch coupled between the adapter and system nodes, a second isolation switch coupled between the battery and system nodes, a boost converter, and a controller. The controller turns off the first isolation switch and turns on the second isolation switch during a battery mode, activates the boost converter when an adapter voltage is detected, turns off the second isolation switch when the system voltage rises above the battery voltage, and turns on the first isolation switch when the system voltage rises to an operating voltage level. The boost converter may then be turned off once in the adapter mode. The second isolation switch may initially be turned on partially at a low current level when the adapter is detected, and then turned fully on when the system voltage is at the operating voltage level.

  • Patent number: 10797515
    Abstract: A method controls an UPS with a system having: first and second terminals, a switch having: first and second switch terminals respectively connected to the first and second terminals; first and second thyristors connected between the first and second switch terminals in anti-parallel; and an inverter connected to the second terminal and the energy store. Switch current and a first potential at the first terminal are detected. In a first fault, where the first potential drops past a first rule and the switch current rises above a second rule: a second potential at the second switch terminal is set using the inverter so the switch current becomes zero. Then the switch current is compared with a second threshold, and if it is exceeded, a first check result is positive, otherwise it's negative. When positive, the second potential is reversed.

  • Patent number: 10782721
    Abstract: Embodiments of the present invention may include control methods employed in multiphase distributed energy storage systems that are located behind utility meters typically located at, but not limited to, medium and large commercial and industrial locations. These multiphase distributed energy storage systems can operate semi-autonomously, but may be in frequent contact with a cloud-based optimization engine that is configured to develop energy control solutions based on various data inputs and to communicate these energy control solutions to one or more of the distributed energy storage systems. Due to characteristics of the electric load location and/or the use of on-site power generation, imbalances in the power draw per phase can be created within the electric load location. Therefore, embodiments of the invention may include systems and methods that are used to control and/or limit the imbalance in power flowing through one phase versus other phases at the electric load location.
