  • Patent number: 6107560
    Abstract: A solar cell array used in a photovoltaic power generation apparatus for housing covers a relatively large outside area for installation, and a considerably large earth capacitance Ca exists between the solar cell array and the ground. Further, as an inverter for converting direct-current electric power generated by the solar cell array into alternating-current electric power, a transless-type inverter is used for reducing cost. Therefore, a slight leak current flows via the earth capacitance Ca, which may cause undesirable operation of an earth leakage circuit breaker inserted between the inverter and a commercial AC power system. In the photovoltaic power generation apparatus of the present invention, by designing it so that the relationship between the earth capacitance Ca[.mu.F] and leak current detection sensitivity EL[mA] of the earth leakage circuit breaker is Ca<EL/3, the undesirable operation of the earth leakage circuit breaker due to the leak current is prevented.

  • Patent number: 5860818
    Abstract: An electrical connecting member is provided with a holding member made of an electric insulating material and a plurality of conductive members held by the holding member in a state of being insulated with each other. One end of each of the conductive members is exposed on one surface of the holding member and the other end of each of the conductive members is exposed on the other surface of the holding member. The conductive members have portions exposed from the holding member, the length of which is longer than the thickness of the holding member. These exposed portions are easily deformed by the pressure force exerted at the time of connecting electric circuit components to reduce the coupling load even when there is irregularity in the heights thereof or unevenness in the junctions of the objects connection, hence enabling high density connections between the electric circuit components.
