Definitions
- An uninterruptible power supply is an uninterruptible power supply that supplies AC power to a load using power supplied from an AC power supply or a power storage device, and converts the AC power supplied from the AC power supply to DC.
- the control circuit When starting the inverse converter, the control circuit maintains the ratio between the voltage value of the output voltage of the inverse converter and the frequency of the output voltage of the inverse converter at a predetermined value, while maintaining the output voltage of the inverse converter. Each of the voltage value and frequency is gradually increased.
- the DC bus 5 is connected between the output terminal of the converter 4 and the input terminal of the inverter 7 to transmit DC power.
- Capacitor 6 is connected to DC bus 5 and stabilizes DC voltage VDC of DC bus 5.
- the inverter 7 is controlled by the control circuit 14 and converts the DC power received from the DC bus 5 into AC power and outputs it to the output terminal.
- the semiconductor switch 15 When the inverter 7 fails, the semiconductor switch 15 is turned on instantaneously, and AC power from the AC power source 51 is supplied to the load 54 via the semiconductor switch 15 and the transformer 53. After the switch 10 is turned off and the switch 16 is turned on, the semiconductor switch 15 is turned off. Thereby, AC power from the AC power supply 51 is supplied to the load 54 via the switch 16 and the transformer 53, and the operation of the load 54 is continued.
- FIG. 3 is a circuit block diagram showing a configuration of the uninterruptible power supply according to Embodiment 2 of the present invention, and is a diagram compared with FIG. Referring to FIG. 3, this uninterruptible power supply is different from the uninterruptible power supply of FIG. 1 in that control circuit 14 is replaced with control circuit 14A.
