With an inverter device (1), even when a phase shift is produced between output current and output voltage, it is still possible to control the output current and supply reactive power effectively. To do so, the inverter device (1) has an inverter section (2) that is comprised of a bridge circuit. Also, between two connecting wires (S11 and S12), a clamp section (5) that is formed with a series circuit, in which a fifth switching element (Q5) where a fifth diode (D5) is connected in anti-parallel and a sixth switching element (Q6) where a sixth diode (D6) is connected in anti-parallel are connected in series so that the conducting directions of the fifth diode (D5) and the sixth diode (D6) become opposite to each other, is provided. Also, a control section (6) to supply pulse signals for on/off switching to the first switching element (Q1) to the sixth switching element (Q6) is provided. |
