<P>PROBLEM TO BE SOLVED: To provide an inverter device which can suppress a rise of the temperature of a smoothing capacitor without causing an increase of the capacity of the smoothing capacitor. <P>SOLUTION: In the inverter device in which a phase unit is constituted by accommodating a switching element module for constituting each phase of an inverter, a short-circuit protecting fuse, and a constituent element of the smoothing capacitor or the like in a unit case per phase, and which is constituted by combining a plurality of sets of the phases and connecting them to a DC bus bar arranged outside the unit case, a DC input terminal is arranged at a middle connecting part for connecting the switching element module in each phase unit case and the smoothing capacitor, and the DC input terminal and the DC bus bar are connected by a connecting conductive plate. <P>COPYRIGHT: (C)2010,JPO&INPIT |
