PURPOSE:To improve the working efficiency of a power supply device by providing a switch circuit between a power supply unit and a power supply input of a circuit device together with a connection line and performing the stop and switching of a power supply in accordance with the state of load. CONSTITUTION:A direct current is supplied to (n) units of power supply units P1-Pn from a high voltage DC power supply E via a common feeder A. The direct current is converted into the voltage by each power supply unit and supplied to electronic circuit devices L1-Ln via feeders B1-Bn, switch circuits S1-Sn and feeders C1-Cn respectively. circuits S1-Sn are connected to each other every adjacent ones via connection lines D1-Dn. A load current is detected by detecting circuits Q1-Qn. A CPU stops the actuation of one of units P1- Pn when the load of the relevant unit is reduced less than a prescribed level. Thus the load device which receives so far the corresponding power supply unit is switched to the output of another power supply unit.

When the current consumption of Ln changes, all power supply units P1 to Pn are in operation even when the current consumption is extremely small. In general, the power efficiency of a power supply device deteriorates as the load current becomes smaller than its rated value, so each power supply unit P+ to Pn continues to operate in an inefficient state with a load lower than its rated load, resulting in a lower overall efficiency. There were drawbacks that made it worse. In particular, when the large electronic device is an electronic exchange, the current consumption of each electronic circuit device varies greatly depending on the call traffic being processed.
During times of heavy traffic, a current close to the rated output is supplied, but during times of low traffic, a small current is supplied, resulting in large power losses. Furthermore, if a failure occurs in one of the power supply unit b P 1 to Pn (7),
The electronic circuit device connected to the power supply unit stops operating and is excluded from the operation of the large electronic device, resulting in low reliability.
