Photovoltaic device and operating point control circuit device for photovoltaic cells or other power supply elements connected in series

In a photovoltaic device or an operating point control circuit in which a current is output from a corresponding power supply cell or capacitor to between output terminals by periodically cutting off switching elements which are connected in series to a plurality of power supply cells and/or capacitors connected in series between the output terminals via inductors, cutoff duty ratios of all the switching elements are uniformly fixed to the same value in one cycle in which all the switching elements are cut off once.. . ... Tokyo Metropolitan University

Solar power generation system

A solar power generation system includes: solar cells, or solar cells and at least one capacitor, connected in series between output terminals; an accompanying circuit provided for each of the solar cells, or each of the solar cells and each of the at least one capacitor, the accompanying circuit including an inductor and a switching device arranged in series; and a power generation operating point control device. The solar cells, or the solar cells and the at least one capacitor, are divided into units, of which adjacent units share one of the solar cells or one of the at least one capacitor. ...

Electric power generation operation point control circuit device

Three or more photovoltaic cell units connected in series include a unit holding a voltage between output terminals, a first voltage holding unit group having a voltage holding unit holding a voltage between an anode-side terminal and a cathode-side terminal for each photovoltaic cell unit set with respect to each set of the (2k+1)th and (2k+2)th photovoltaic cell units connected in series to each other counted from the anode side, and a second voltage holding unit group having a voltage holding unit holding a voltage between an anode-side terminal and a cathode-side terminal for each photovoltaic cell unit set with respect to each set of the (2k+2)th and (2k+3)th photovoltaic cell units connected in series to each other counted from the anode side.. . ... Tokyo Metropolitan University

Electric power generation operation point control circuit device and multi-stage electric power generation operation point control circuit device

An electric power generation operation point control circuit device includes: a first capacitor connected in parallel to a photovoltaic cell via the pair of electrode connection terminals between the pair of output terminals; a first switching element connected in parallel to the photovoltaic cell via the pair of electrode connection terminals and the inductor between the pair of output terminals and causing a conduction state or a non-conduction state between the connected terminals; and a second capacitor connected in series to the first capacitor between a first electrode connection terminal and a first output terminal and causing the conduction state or the non-conduction state between the connected terminals.. . ...
