Abstract

The invention provides a kind of inverter device which can employ one location for both detection of input current and regenerative current. In order for this purpose, the invention employs current inductor to detect the high frequency current flow of the smooth capacitor connected to the direct bus and the current detection circuit can get the detected current value Ia form the current inductor during the connecting at IGBT 8 by the clock signal supplied by the output control circuit, then to detect the input current value according to the said current value Ia and the previously acquired data table for associated relationships. During the breakage of IGBT 8 to the connection of IGBT 7, if the current detection circuit can get the detected current value Ib from the current inductor, it can detect the regenerative current based on the current value Ib and the data table.
