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 …

Why it's free to use
- Filed June 6, 1998 and granted February 27, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 6, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 6, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
