Abstract
A generator-motor apparatus () includes a control circuit (), an alternator (), electrode plates (), and switching devices (SWto SW). The electrodes plates () have a substantial horseshoe shape, and are provided on an end surface of the alternator () so as to surround a rotating shaft (A) of the alternator (). Each of the switching devices (SWto SW) is formed by sandwiching a MOS transistor between two electrodes, and has a can structure for sealing the internal space of the switching device using a resin. The switching devices (SW, SW, SW) are directly attached to the electrode plate () by means of soldering, and the switching devices (SW, SW, SW) are directly attached to the electrode plate () by means of soldering. The control circuit (2% controls the switching devices (SWto SW). The switching devices (SWto SW) drive the alternator () as an electric motor or an electric power generator.
