  • Patent number: 10284139
    Abstract: A system for measuring the power or energy loss in a photovoltaic array due to soiling, which is the accumulation of dust, dirt, and/or other contaminants on the surfaces of photovoltaic modules, comprising: a pair of photovoltaic reference devices placed within or near the photovoltaic array and co-planar to the modules comprising the array, wherein one reference device is a module or cell similar to those of the array and is allowed to accumulate soiling at the natural rate, and wherein the second reference device is a module or a cell and is maintained clean; and a measurement and control unit which measures and compares the electrical outputs of the soiled reference device and the clean reference device in order to determine the fraction of power lost by the soiled reference module due to soiling.

  • Patent number: 10277139
    Abstract: A transformer is composed of three or more windings magnetically coupled. An AC/DC converter (2) for converting AC power of an AC power supply (1), a capacitor (3), and a switching circuit (4) are connected to one winding (6a), and a switching circuit (8) or (30) for power conversion of a DC power supply is connected to at least one of the other windings. Voltage of the capacitor (3) or the AC power supply (1) is detected. On the basis of the detected value thereof, the operation state of each switching circuit (4), (8), (30) is determined by an operation state determination circuit (101). On the basis of a result of the determination, the power supply is switched among the AC power supply (1) and the DC power supplies (11) and (34) by an output switch circuit (103).

  • Patent number: 10232735
    Abstract: A control device for a power supply system includes a pre-charge unit, the power supply system having a main electric storage device, a smooth capacitor, a step-up circuit, an open-close switch, a voltage source and a regulation element. The regulation element regulates a current flowing from the smooth capacitor toward the open-close switch. The voltage source is connected to a connection portion between the open-close switch and the step-up circuit, and outputs an output voltage higher than a voltage of the main electric storage device before the open-close switch is shifted from a disconnection state to a connection state. The pre-charge unit executes a pre-charge of the smooth capacitor by supplying electric power from the voltage source to the smooth capacitor before the open-close switch is shifted from the disconnection state to the connection state.
