テムは、第３図の如き構成のものが広く知られている。Conventional technology and its problems A DC power supply system that supplies power to a load using the electromotive force of a large F3 m battery, floats charges a storage battery, and discharges the storage battery when the electromotive force stops, thereby continuously supplying power to the load. A configuration as shown in FIG. 3 is widely known.

短絡するようにＰＪＩｔ成されている。In other words, in Figure 6, Sun 1! The electromotive force of the battery is supplied to the load 2 via the diode 3 and also to the storage battery 1'
When the electromotive force stops, the storage r1 battery 1' is discharged to supply power to the load 2. In addition, in order to prevent the storage battery 1' from being overcharged by the power of the solar battery, when the storage battery voltage exceeds the Zener voltage Vz of the voltage regulator diode 5, the thyristor 4 is fired to short-circuit the output of the thick ntt battery. PJIt has been established as follows.

) As shown in Figures 4(a) and 4(b), when there is a lot of solar radiation, the output of the thyristor 4 is short-circuited by the thyristor 4, and the electromotive force is not used effectively. Since the discharge time is longer and the final discharge voltage is lower than when the amount of solar radiation is low, the voltage fluctuation ΔV with respect to the load is from the Zener voltage Vz of the voltage regulator diode 5 to the final discharge voltage, and varies depending on the amount of solar radiation. There was a drawback. Furthermore, during periods of high solar radiation, the storage battery 1' is charged in a short time and then discharged for a long time, resulting in a shortened lifespan.
