めることがで會る電＃装置を提供することである。A conventional power supply device has a plurality of independent power supplies for individually supplying power to a plurality of loads making up one system. However, in a power supply device with such a configuration, if 1t or 2 or more of the multiple independent power supplies fail,
Therefore, the first aspect of this invention is that it is possible to improve the reliability of the system. The purpose is to provide a telephone device for communication.

る。An embodiment of the present invention is shown in the drawings. That is, this power supply device has a plurality of loads 21 to 21 constituting one system.
In a power supply device having a plurality of independent power supplies J[1m-1m, which individually supply power to 2n, seven independent power supplies among the plurality of independent power supplies 1lls to 1n, It is the voltage drop below a predetermined value of the voltage of lkl. Detected by the output circuit 4a, the load 2b corresponding to the independent power supply 1b whose voltage has dropped is responded to the output of the voltage detection circuit 4 from another independent power supply 111m of the plurality of independent power supplies 1m to 1in. When the power supply is normal, power is supplied by closing the switch circuit 3m which is in the open state flK. Other independent power supply IC~1m, 1
Similarly to the above, voltage detection circuits 4b to 4m and switch circuits 3b to 3m are provided for aK, and each of the independent types '#ll to IEI has a margin of more than twice that.

The voltage output of 11F is connected to a backflow blocking diode 61, respectively.

を補償するという関係でなければシステムは機能する。In this way, in the electric IIA device of this embodiment, when one of the plurality of independent power supplies 11 to 1m breaks down, it is compensated for by another one of the plurality of independent power supplies. Even if one of the independent types #1a to #1i breaks down, the corresponding loads 2 to 2 will not stop operating, and the functionality of the entire system will not be impaired, increasing system reliability. We meet for something. Further, even if there are two or more failed devices, the system will function unless there is a relationship in which one of them compensates for the other.

The system stops working at all.

ばよい。In order to prevent this, the system should be inspected more often. In other words, by increasing the number of inspections, it is possible to prevent two to five of the independent power supplies 11 to 1n from failing within the same period. Alternatively, an alarm may be issued as soon as the voltage detection circuits 4 to 4n operate to prompt repair of the power supply.

ＩＩ腋にすればよい。Note that this embodiment is most effective in cases where there is no point in operating other loads when one load stops, and in cases where it is meaningless to operate other loads when one load stops, and in cases where the system only partially operates and performs a certain function. This is considered to be inappropriate, so these four systems can be divided into Kf systems for each function, and each subsystem can be configured as shown in the drawing. In addition, if the subsystem has one power supply and one load,
Two such subsystems can be combined to create a mutually fixed I

長くすることができる。In addition, this method not only mutually compensates multiple independent #1 m-1n to increase the reliability of the entire system, but also
For example, it is also effective when each independent power source is compensated for power outage by a backup power source, such as in a disaster prevention system. That is,
If a power outage occurs and the switch is made to the standby power source, the discharge time of each load will vary depending on the state of charge of the standby power source or variation in power consumption. The backup power supply will compensate for this by averaging the operating time of each load, increasing the amount of time the entire system is healthy.

できるという効果がある。As described above, in the power supply device of the present invention, in a power supply device having a plurality of independent power supplies that individually supply power to the loads constituting one system, one independent power supply among the plurality of independent power supplies is provided. A voltage detection circuit detects a drop in the voltage below a predetermined value, and outputs the output of the voltage detection circuit from another one of the plurality of independent power supplies to the load corresponding to the independent power supply where the voltage has dropped. The present invention is characterized in that when the switch circuit is closed in response to Ki5, power is supplied to K and K, which has the effect of increasing the reliability of the system.
