Abstract
Main arrays (MA1-MAm) of solar cells (2) are provided so as to correspond to shunt circuits (SM1-SMm), respectively. Charge arrays (CA1-CAn) are provided so as to correspond to shunt circuits (SC1-SCn) and charging circuits (CH1-CHn), respectively. Each shut circuit operates independently from other shunt circuits, and each charging circuit operates independently from other charging circuits.
Claims7
A power supply controller for controlling power supply from a plurality of solar cell arrays and a battery to a load and controlling charging of the battery using the plurality of solar cell arrays, comprising:
- a plurality of shunt circuits provided so as to correspond to the plurality of solar cell arrays, respectively, for controlling power supply from the corresponding solar cell arrays to the load;
- and
- one or more charging circuits provided so as to correspond to a part or all of the plurality of solar cell arrays, respectively, for controlling the charging of the battery using the corresponding solar cell arrays,
- wherein the plurality of shunt circuits and the one or more charging circuits are separately and independently operated based on preset threshold values.
