"textContent": "The application relates to a method for operating an inverter that has an H4 bridge circuit having a first half-bridge and a second half-bridge for converting an input-side direct voltage into an output-side alternating voltage and is configured for supplying electrical power of a direct voltage source with a variable potential relative to a ground potential, for example, of a photovoltaic generator with a leakage capacitance with respect to ground, to an alternating voltage grid. The method includes unipolar pulse-width-modulated clocking for each of the two half-bridges for the half-wave generation of substantially sinusoidal half-bridge voltages, and modifying the clocking of the half-bridges in a transition region around a zero crossing of the output-side alternating voltage to damp a leakage current (IA) that flows through the leakage capacitor to ground. The application also relates to an inverter and to a computer program product.",
