The invention relates to an inverter (1) for a DC power source, capable of supplying, from the DC voltage signal of the power source, an AC voltage signal having a frequency which corresponds to the frequency or to a multiple of the frequency of the electric network into which said voltage signal is intended to be injected, characterised in that the inverter comprises at least one DC-DC converter (10; 10A, 10B) which is capable of supplying a DC voltage signal in the form of arches that are modulated to the frequency or to a multiple of the frequency of the signal circulating on the electric network, and in that, downstream of the DC-DC converter, the inverter comprises what is referred to as a switching block (11), including at least two switches (T1, T2, T3, T4), preferably transistor-type switches, the function of which is to allow the current through and to block same alternately, in accordance with the polarity of the voltage of the electric network, in order to supply at the output of the block on the electric network a voltage signal at the frequency or at a multiple of the frequency of the electric network, said signal having a shape which corresponds to the shape of the signal of the electric network. |
