<p>A multilevel inverter device comprises: a series circuit of first and second switch elements (21, 22) connected between the high and low voltage side terminals of a DC power supply (2); a series circuit of two capacitors (11, 12) connected in parallel to the first and second switch elements (21, 22) so as to generate an intermediate voltage of the DC power supply (2); and a single first bidirectional switch element (100) connected between a junction (P1) of the two capacitors (11, 12) and a junction (P2) of the first and second switch elements (21, 22). The bidirectional switch element (100) has a horizontal transistor structure using GaN/AlGaN.</p> |
