Abstract
An inverter device for changing direct current to alternating current for supplying to an electric motor which may be employed in an electric automobile. This inverter device includes a plurality of switching units, a cooling support member, capacitors, and pairs of first and second conductive plates. Each of the switching units has a box-like casing mounted on the cooling support member, and includes a positive switching element, a negative switching element connected in series, and positive and negative terminals. The positive and negative terminals are exposed on the upper wall of the casing. Each of the capacitors is arranged over an upper wall of the casing of a corresponding one of the switching units, and has positive and negative charge/discharge terminals. The first conductive plate of each pair connects the positive terminal of one of the switching units with the positive charge/discharge terminal of a corresponding one of the capacitors, while the second conductive plate of each pair connects the negative terminal of one of the switching units with the negative charge/discharge terminal of a corresponding one of the capacitors.
