を満し得ていない状況である。BACKGROUND OF THE INVENTION 2. Description of the Related Art In recent years, electrical and electronic equipment has become increasingly lighter, thinner, and smaller, and along with this, there has been an increasing demand for smaller, lighter, and thinner power supplies for equipment. In addition to this, the demand for portable and cordless equipment is increasing rapidly.
There is a need for a power source that can be used anywhere and at any time with peace of mind. For example, the most common commercial power source cannot be used without wires, giving rise to demands for portability and cordless power. Also, solar cells cannot be used without light.
The above requirements cannot be met because dry batteries have a limited capacity, lead-acid batteries, etc. are heavy and large, and require dedicated charging circuits and equipment that can strictly control the voltage due to the danger of overcharging. It's a situation.

となっている。On the other hand, in order to compensate for the shortcomings of solar cells, various methods have been proposed and adopted in which solar cells are combined with rechargeable storage batteries and capacitors, but since they can only be charged when illuminated,
This requires a large safety factor, which is a constraint on optimal equipment design.
