An uninterruptible power supply including a controlled rectifier for receiving a first AC voltage and for converting the first AC power voltage into a first DC output voltage, a battery for supplying a second DC output voltage, a voltage step-up chopper connected to receive the first DC output voltage and the second DC output voltage as a DC input voltage for stepping up the DC input voltage to produce a stepped-up voltage, and an inverter connected to receive the stepped-up voltage for converting the stepped-up voltage into a second AC voltage which is the AC output of the uninterruptible power supply. Additionally, a method for starting the uninterruptible power supply is disclosed. |
