  • Patent number: 10317477
    Abstract: An inspection method of a secondary battery includes a charging step, an aging step, a pre-inspection discharge step, a voltage adjustment step, a self-discharge inspection step, and a deficiency determination step. A discharge condition in the pre-inspection discharge step is determined so that a voltage difference accumulation value Vs satisfies a predetermined range. The voltage difference accumulation value Vs is calculated by accumulating a value obtained by subtracting an output voltage from a predetermined voltage over a duration from start of the pre-inspection discharge step to end thereof.

  • Patent number: 10305322
    Abstract: When three phase AC voltages (Vi1 to Vi3) from a commercial AC power supply (51) become abnormal, a control circuit (6) of an uninterruptible power supply device provides an OFF command signal to first to third switches (1a to 1c), and causes first to third power converters (2a to 2c) to output first to third direct currents, respectively, and quickly extinguish arcs in the first to third switches (1a to 1c). On this occasion, polarities of the first to third direct currents are the same as polarities of currents (Is1 to Is3) flowing into the first to third switches (1a to 1c), respectively, and the sum of values of the first to third direct currents is 0.

  • Patent number: 10256635
    Abstract: The invention provides a method and system for operating a solar farm inverter as a Flexible AC Transmission System (FACTS) device—a STATCOM—for voltage control. The solar farm inverter can provide voltage regulation, damping enhancement, stability improvement and other benefits provided by FACTS devices. In one embodiment, the solar farm operating as a STATCOM at night is employed to increase the connectivity of neighboring wind farms that produce peak power at night due to high winds, but are unable to connect due to voltage regulation issues. The present invention can also operate during the day because there remains inverter capacity after real power export by the solar farm. Additional auxiliary controllers are incorporated in the solar farm inverter to enhance damping and stability, and provide other benefits provided by FACTS devices.

    Abstract: Systems and methods for resolving fault detection in a control system is provided. The system includes an I/O module operably connected to a first, second, and third microcontroller for transmitting data. The first microcontroller is in an active state, i.e., in control, while the remaining controllers are in an idle state. The system further includes an event generator for generating an event indicative of a fault occurrence, and a means for detecting a fault event. The system also includes a means for reassigning a controller, wherein upon detection of a fault event in both the first and second controllers, the means for reassigning a controller changes the state of the third controller to active, leaving the remaining controllers idle or in a shutdown state, thereby effectively assigning control from the first controller to the third controller.

  • Patent number: 10149357
    Abstract: Employed within an LED driver operating from the AC power line, the invention controls both input current and output power. With this regulation circuit, input current appears purely resistive, precisely tracking the input voltage waveshape. At the same time, it provides good line regulation and inherent phase dimmer compatibility, requiring no special circuitry to detect and handle a dimmer.
