の用途は増加の一途をたどっている。(Prior art and its disadvantages) Conventionally, a solar cell charges a secondary battery with power generated by a solar cell, and when the voltage of the power generated by the solar cell decreases, the secondary battery supplies charging power to a load. The use of power supplies continues to increase due to the fact that there is no regional deflection difference, which is a characteristic of solar cells, and that no manual work is required to start driving the load.

is connected to. That is, it is a charging circuit that charges the secondary battery 3 with the power generated by the solar cell 1. Also, the solar cell 1
A resistor RzRz, Rz and a reversing l are connected between the and the secondary battery 3.
- Voltage detection means 4 including a transistor Tr is provided, and this voltage detection means 4 divides and detects the open circuit voltage of the solar cell 1, and includes a switching transistor T that drives the load 5.

Then, the secondary battery 3 is charged via the backflow prevention diode 2. Further, the open circuit voltage of the solar cell 1 is divided by the resistors RI and R2 of the voltage detection means 4, and a voltage is applied to the base of the inverting transistor Tr+.

Therefore, the switching transistor Trz is turned on, and power from the secondary battery 3 is supplied to the load 5. That is, the load 5 is driven inside the package, and even if the user actually wants to use this solar battery power supply device, the amount of charge in the secondary battery 3 is extremely small, so the load 5 cannot be driven effectively. I couldn't do it.
