Abstract
A generator-motor apparatus includes a control circuit, an alternator, electrode plates, and switching devices. 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 of the alternator. Each of the switching devices 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 are directly attached to the electrode plate by means of soldering, and the switching devices are directly attached to the electrode plate by means of soldering. The control circuit controls the switching devices. The switching devices drive the alternator as an electric motor or an electric power generator.
