Abstract:
A three-level inverter includes a first semiconductor switching element disposed between a direct-current high potential terminal and an alternating-current output terminal, a second semiconductor switching element disposed between a direct-current low potential terminal, which is paired with the direct-current high potential terminal, and the alternating-current output terminal, first and second reflux diodes which are disposed reverse-parallelly with the first and second semiconductor switching elements, respectively, and a semiconductor circuit which controls gate voltages of the first and second semiconductor switching elements by selectively applying thereto a direct-current intermediate voltage which is given to a direct-current intermediate potential terminal. Inductance elements are connected in series to the first and second reflux diodes, respectively.

Claim (Index 1):
A three-level inverter comprising:\n a first semiconductor switching element provided between a direct-current high potential terminal and an alternating-current output terminal and configured to be turned on/off during a positive voltage output mode; a first reflux diode disposed reverse-parallelly with the first semiconductor switching element; a second semiconductor switching element provided between a direct-current low potential terminal, which is paired with the direct-current high potential terminal, and the alternating-current output terminal and configured to be turned on/off during a negative voltage output mode; a second reflux diode disposed reverse-parallelly with the second semiconductor switching element; a semiconductor circuit configured to control gate voltages of the first and second semiconductor switching elements by changing a potential of the alternating-current output terminal in correspondence to a direct-current intermediate voltage obtained by dividing a direct-current voltage to be applied between the direct-current high potential terminal and the direct-current low potential terminal; and first and second inductance elements connected in series to the first and second reflux diodes, respectively.
