Abstract
There are provided an output inverter for single phase which can detect a current with high precision through a smaller number of components, and an output current detecting method thereof. A first current detector (6) is disposed between a positive electrode P side of a DC power supply and a parallel connector (1) in a first arm (8), a second current detector (7) is disposed between a negative electrode N side of the DC power supply and a parallel connector (4) in a second arm (9), a current in a first convection mode is detected by the first current detector (6), a current in a second convection mode is detected by the second current detector (7), and an output current is detected from signals output from the first current detector (6) and the second current detector (7).
