SOLUTION: A converter 11 is connected to an AC power source through an input-side filter 2 to convert AC to DC. An inverter 12 is connected to the converter 11 through a DC bus line 15, and converts DC to AC which is supplied to a load through an output-side filter 3. Neutral points of input-side and output-side capacitors 22 and 32 are connected together using a connection line 16, and the connection line 16 is grounded using a capacitor 5, resulting in reduced leakage current caused by stray capacitance.

A control circuit 200 generates in the capacitor 102 a voltage which cancels a common mode voltage VCEN that occurs at the capacitor 5 and a common mode voltage Vc that occurs at the DC bus line 15 to suppress the leakage current that reflows from a converter 1 to an AC power source and a load.

摘要： PROBLEM TO BE SOLVED: To provide a parallel-operation uninterruptible power supply system wherein a cross current is prevented from flowing between uninterruptible power supplies when operation is switched between commercial synchronized operation and stand-alone operation. SOLUTION: Any one of uninterruptible power supplies functions as a master and controls output voltage phase as a reference and the other ones perform slave operation to control current so that they are synchronized with the reference voltage phase of the master. When the uninterruptible power supply as the master becomes incapable of commercial synchronized operation, an uninterruptible power supply as a slave capable of commercial synchronized operation becomes a master and carries out output voltage phase control. The former master that became incapable of commercial synchronized operation performs slave operation. When all the uninterruptible power supplies in parallel operation become incapable of commercial synchronized operation, a master that performs stand-alone operation in stand-alone mode with a fixed frequency is determined.
