は第５図の電圧−電流特性グラフに示す通りであった。In order to protect the device itself, power supply circuit devices that have constant voltage characteristics as general power supply equipment have a drooping system that reduces the output voltage when the power consumption exceeds the rated current value. characteristics are given. That is, in the case of a device using a thyristor-controlled rectifier circuit as a conventional power supply circuit device of this kind, as shown in FIG.
It consists of a series circuit consisting of a fixed resistor 16 and an operational amplifier 14, and a thyristor-controlled rectifier circuit 15 to provide a predetermined drooping characteristic, and its drooping characteristic is shown in the voltage-current characteristic graph in Figure 5. It was as shown.

に見合った電力容量での契約が可能となる。In this way, in the case of a power supply circuit device with a predetermined drooping characteristic in a conventional configuration, a preset maximum input power capacity,
When comparing increases and decreases in power consumption in the power demand load device, even if there is a significant difference between the two, the rated capacity of the power supply circuit device will always remain at a constant value. Therefore, as a specific power demand for this purpose, for example, when the initial power load capacity is small and the final power load capacity is expected to be large due to appropriate construction work over a certain period of time, in other words, the power demand is Even in the case of large fluctuations, the contracted power capacity with the power company is fixed in advance based on the maximum operating capacity of the power supply equipment, or in this case, the final power capacity, which can lead to unnecessarily high power costs. There is a disadvantage that it is. In such a case, if the power supply value of the power supply circuit device can be reduced based on the maximum power load capacity value at the time of the contract, or by the maximum power load capacity value in each case, it will be possible to reduce the power supply value to meet the power demand of the load. It will be possible to make a contract with a new power capacity.
