Title: UNINTERRUPTIBLE POWER SUPPLY UNIT
Abstract:
A generation circuit (21) is configured so as to generate an output voltage command value Vor* for an inverter (7) on the basis of a three-phase reference value Vr, a zero-phase reference value, a detected value of a current sensor (8), and a detected value of a voltage sensor (9). A compensation circuit (38a) is configured so as to compensate a voltage drop across a three-phase AC line (13) when a three-phase AC power is supplied to an AC load (2) from the inverter (7). A correction unit (34) is configured so as to correct the output voltage command value Vor* on the basis of a compensation command value Vol. A control circuit (36) is configured so as to control the inverter (7) on the basis of an output voltage command value Vo* corrected by the correction unit (34).
