  "textContent": "The method involves increasing direct current voltages (+U-ZL, -U-ZL) by a step-up converter circuit (H), if the direct current voltage is lower than a peak-to-peak maximum of a network voltage (U-Netz). Intermediate circuit voltages (+U-ZH, -U-ZH) are lowered to a voltage required in a network (N) by a step-down converter circuit (T). The direct current voltages are dynamically increased to a value required in the network by the step-up converter circuit. An approximately sinusoidal voltage curve is temporarily supplied for the intermediate circuit voltages. An independent claim is also included for an inverter for converting a direct current voltage of a solar generator into an alternating current voltage for supplying power to a network.",
