Parallel inverter device

摘要

PROBLEM TO BE SOLVED: To be able to detect fusion of a fuse without enlarging a device.SOLUTION: A parallel inverter device 1 comprises a first inverter 10 for converting a DC power input via a first fuse 11 from a DC power supply 3 into an AC power to output a first current; a second inverter 20 for converting a DC power input via a second fuse 21 from the DC power supply 3 into the AC power to output a second current; and an abnormality detection part 43 for detecting fusion of the first fuse 11 or the second fuse 21 based on a direction and a magnitude of the first current, and a direction and a magnitude of the second current.SELECTED DRAWING: Figure 1
