Abstract

PURPOSE:To prevent the consumption of an unnecessary battery by stopping a DC/DC converter or a DC/AC inverter when load is brought to a preset state or less the service interruption of a commercial power supply. CONSTITUTION:When service interruption is generated, an interruption signal is transmitted instantaneously over a control section (e) from a service interruption detector (g). When the value of output currents obtained from an output current detector (h) reaches an expected value or more at that time, this device is supplied with the energy of a battery (f), and the device continues an output. When output currents acquired from the output current detector (h) reaches the expected value or less, on the other hand, the control section (e) stops the oscillation of the DC/DC converter or the DC/AC inverter. That is, when the load side of the uninterruptible power supply equipment is stopped completely or brought to a standby state and output currents reach the expected value or less, the oscillation of the DC/DC converter or the DC/AC inverter is stopped automatically, thus preventing the consumption of a battery.

The operation of this device is that when commercial power is supplied, the commercial input is fed from the terminal 1 to the rectifier 3, and the DC/DC converter or DC/A,C inverter 4 receives the DC input from the rectifier 3. Output is made to the load from output terminal 2. The control unit 5 controls the operation of 4, and the battery 6 is floating-charged from the rectifier 3. In addition, if a power outage occurs, the DC power supply from the battery No. 6 will be used to connect the DC/DC converter or DC/A.
The C inverter 4 outputs an output to the output terminal 2 while being under the operation control of the control section 5. By the way, in such a power supply device, when the load side is completely stopped or in a standby state, there is a problem that the battery energy is consumed because power is supplied from the battery in the event of a power outage.
