Title:
CIRCUIT DEVICE OF SOLAR CELL
Document Type and Number:
Japanese Patent JPH09117077
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To fabricate a circuit device which can optimumly adapt the power generated by a solar battery to the power required for an ohmic load or induction load by a simple means. SOLUTION: This circuit device, having a first solar battery series circuit A and at least one second solar battery series circuit B parallelly connected to the first circuit A, uses electric energy generated by the solar batteries for the operation of an ohmic load or induction load L. Different from the publicly known circuit device in which series circuits integrated with one parallel circuit have no-load voltages of nearly the same level, the series circuits A, B adapt a current/voltage characteristic of the load L to various kinds of no-load voltages which can be generated. It is preferred that one or a plurality of reverse flow preventive diodes 16 should be inserted in one or a plurality of the series circuits A which have a lower no-load voltage.
