  • Patent number: 9345160
    Abstract: Provided is an electronic device that is provided with a filter circuit that suppresses the effects of electromagnetic noise propagated through space from a circuit board and reduces parasitic inductance, and can output a voltage with adequately reduced noise. To solve the above problem, in an electronic device provided with a cabinet (101), a circuit board (132) provided in the cabinet, an output terminal (122) that passes through a through hole provided in the cabinet and outputs the output of the circuit board to the outside, the present invention constructs a loop composed of a filter means (142) having a filter capacitor (142a), an output terminal, a cabinet, and wires (142b, 142c) for connecting these parts. The wire (142c) connected to the cabinet is connected to a position close to the output terminal, and reduces the size of the loop. In addition, a shield (102) is provided between the filter means and the circuit board.

  • Patent number: 9300133
    Abstract: Various techniques are employed alone or in combination, to reduce the levelized cost of energy imposed by a power plant system. Solar energy concentrators in the form of inflated reflectors, focus light onto photovoltaic receivers. Multiple concentrators are grouped into a series-connected cluster that shares control circuitry and support structure. Individual concentrators are maintained at their maximum power point via balance controllers that control the flow of current that shunts this series connection. DC current from clusters is transmitted moderate distances to a centralized inverter. The inductance of transmission lines is maximized using an air-spaced twisted pair, enhancing the performance of boost-type three phase inverters. Cluster outputs are separate from individual inverters in massively interleaved arrays co-located at a central location.
