CHARGING POWER SUPPLY DEVICE USING SOLAR BATTERY

摘要

PURPOSE: A charging power supply device using a solar battery is provided to charge a battery for a portable telephone, a portable computer, or a car using a power generated by the solar battery. CONSTITUTION: A first solar battery(20) generates and supplies a charging power for charging a battery(10) to the battery. A charging battery(30) charges and provides the power generated by the first solar battery(20) to a special charging capacitance to the battery(10). A charging power controller(40) intercepts the charging power which is provided from the first solar battery(20) or the charging battery(30) to the battery(10) when a generation power of the solar battery(20) is less than a set value. A second solar battery(50) generates and supplies a charging power for charging a battery(10) to the battery in a state that the second solar battery(50) is connected to the charging power controller(40) in series. A reverse current prevention diode(D2) prevents a reverse current flowing from the battery(10) to the second solar battery(50).
