Inverter device

摘要

An inverter device includes; a switching element; a plurality of flyback diodes each connected in parallel with the switching element; a first conductor plate connected to anode terminals of the flyback diodes and to one side of the switching element; and a second conductor plate connected to cathode terminals of the flyback diodes and to the other side of the switching element. Each of the flyback diodes is formed in a polygonal shape, and the two flyback diodes in each pair of the flyback diodes that are arranged in mutually adjacent positions are arranged so that a vertex of one opposes a vertex of the other.

1. An inverter device, comprising:
a switching element having a front side surface and a back side surface; a plurality of flyback diodes each connected in parallel with the switching element; a first conductor plate connected to anode terminals of the flyback diodes and to the front side surface of the switching element; and a second conductor plate connected to cathode terminals of the flyback diodes and to the back side surface of the switching element; wherein: the switching element and the plurality of flyback diodes are sandwiched between the first conductor plate and the second conductor plate; each of the flyback diodes is formed in a polygonal shape; the plurality of the flyback diodes includes a first flyback diode and a second flyback diode which is arranged closest to the first flyback diode; and the first flyback diode and the second flyback diode are arranged so that a closest part of the first flyback diode to the second flyback diode is a first vertex of the first flyback diode and a closet part of the second flyback diode to the first flyback diode is a second vertex of the second flyback diode.
