Abstract (en)
[origin: WO2007141078A1] The invention relates to an inverter circuit having a primary circuit and a secondary circuit which are galvanically isolated by means of a transformer (T) with the primary circuit having means for clocked connection of a primary winding (N<SUB>P</SUB>) to a DC voltage (V<SUB>IN</SUB>) which is applied to the input of the inverter circuit, and with the secondary circuit having means for connection of a secondary winding (N<SUB>S</SUB>) to an AC voltage (V<SUB>MAINS</SUB>) which is produced at the output of the inverter circuit, with the primary circuit furthermore being connected by means of a first inductor (L<SUB>P</SUB>) to the DC voltage (V<SUB>IN</SUB>), and with the secondary winding (NS) being connected to the AC voltage (V<SUB>MAINS</SUB>) by means of a second inductor (L<SUB>S</SUB>) in series with a first capacitor (C<SUB>S</SUB>), via a full bridge which is formed from four switching elements (S1, S2, S3, S4).
