Uninterruptible power supply
First Claim
1. An uninterruptible power supply comprising:
- rectifier means having input and output terminals for receiving at said input terminals a first AC power signal and converting said first AC power signal into a first DC power signal to produce at said output terminals a DC power output of said uninterruptible power supply;
battery means for supplying a second DC power signal;
controlled rectifier means having input and output terminals for receiving at the input terminals thereof a second AC power signal and converting said second AC power signal into a controlled power output provided at the output terminals thereof;
switch means connected to receive said second DC power signal from said battery for producing said second DC power signal as said DC power output when said first AC power signal is interrupted; and
the output terminals of said rectifier means being connected in series with the output terminals of said controlled rectifier means and said battery means, whereby said first DC power signal and said controlled power output are added and applied to said battery means for charging thereof.

Abstract
An uninterruptible power supply including a rectifier for receiving a first AC power signal and converting the first AC power signal into a first DC power signal to produce a DC power output of the uninterruptible power supply, a battery for supplying a second DC power signal, a controlled rectifier for receiving a second AC power signal and converting the second AC power signal into a controlled power output, and a switch connected to receive the second DC power signal from the battery for producing the second DC power signal as the DC power output power when the first AC power signal is interrupted. Output terminals of the rectifier are connected in series with output terminals of the controlled rectifier and the battery, whereby the first DC power signal and the controlled power output are added and applied to the battery for charging thereof.
