The invention relates to an inverter for inputting sinusoidal currents into an alternating current network. The invention seeks to improve resistance to short circuiting and to reduce the risk thereof. According to the invention, only one switching unit is used to generate a semi-oscillation of a sinusoidal oscillation. In order to generate a positive semi-oscillation of a sinusoidal oscillation, a second switching unit is used in addition to the one used to generate the negative component of a sinusoidal current. As a result, only one switch pertaining to a switching unit is clocked or actuated to generate a positive semi-oscillation. Another switch is clocked or actuated to generate a negative semi-oscillation of a sinusoidal current. The risk of a short circuit between both switches is thus reduced to the period occurring between switching from the positive to the negative or from the negative to the positive semi-oscillation. |
