<p>The inverter circuit (4) has direct current (DC) inputs (42a, 42b), DC outputs (26a, 26b), and a rotor-rectifier (16) connected to a rotor (8) of a dual feed asynchronous generator (2). A mains inverter (20) is connected to a power grid (14), and an intermediate circuit (18) connects one of the DC inputs with the DC outputs. The intermediate circuit has a semiconductor switch (32) between the DC outputs, an intermediate circuit condenser (40) between the DC inputs, and a diode provided between the semiconductor switch and the condenser. An independent claim is also included for a method for operating an inverter circuit.</p> |
