摘要： In this uninterruptible power supply apparatus, even after electric power supply to a load stops due to prolonged power failure time, the operation of an inverter is continued, a DC power supply voltage is generated based on an output of the inverter, and a control circuit is driven by the DC power supply voltage. Therefore, when electric power supply from a commercial AC power supply is resumed during the stop of electric power supply to the load, electric power supply to the load is automatically resumed by the control circuit.

摘要： A power conversion system includes n (n being an integer of 2 or more) power conversion devices (P1 to P4) connected in parallel to a load (4); and a communication line (2) connected to the n power conversion devices (P1 to P4). Each of power conversion devices includes a communication circuit (10) which transmits a load current value detected by a current sensor (37) to each of other (n−1) power conversion devices through the communication line (2), and receives (n−1) load current values transmitted through the communication line (2) from other (n−1) power conversion devices; and an operation circuit (11) calculating a shared current and a cross current of the corresponding power conversion device based on the n load current values. Accordingly, a wiring line is prevented from becoming complicated even when the number of power conversion devices is increased.

摘要： In an uninterruptible power supply system, control sections of three uninterruptible power supply units are connected to one another by communication cables to configure one integrated control unit. The integrated control unit brings three switches into conduction if a bias feeding mode is selected by one arbitrary operation section and brings three switches into conduction if an inverter feeding mode is selected. Therefore, there is no need to separately provide an operation section and a control section for operating and controlling all of the uninterruptible power supply units.

摘要： In an uninterruptible power supply apparatus, a common mode current flowing from nodes (N1 to N3) to a line of a ground voltage (GND) through a stray capacitance (41) of a battery (40) is limited by a common mode reactor (34), and the low-level common mode current passing through the common mode reactor (34) is caused to flow to a virtual neutral line (NL) through a common mode capacitor (37). Therefore, the level of noise caused by the common mode current can be reduced.
