Abstract: An inverter for converting DC power of a generator into grid-conforming AC power includes an inverter bridge circuit and a scanning circuit configured to trace at least one part of a characteristic curve of the generator to determine an MPP power value (PMPP). The scanning circuit is configured, in the case of a derating to a derated power (Pred), to trigger a tracing of the characteristic curve with provision of a first power profile deviating from the derated power (Pred) if an enable signal is present at the inverter, and to indicate a start and an end of the tracing by outputting a start signal and an end signal, respectively. The scanning circuit is further configured to provide a second power profile as AC power upon receiving a start signal, wherein the first power profile has a deviation from the derated power (Pred) with a sign that is opposite to a sign of a deviation of the second power profile from the derated power (Pred).

Abstract: A converter includes a converter inductor, a converter diode, and a converter switch, wherein the converter inductor, the converter diode and the converter switch operate together to receive an input voltage and generate a converted output voltage. The converter further includes a bypass circuit that is connected in parallel with the converter switch; the bypass circuit includes a bypass capacitor connected in series with a diode, wherein a forward direction of the diode is the same as a regular direction of current flow through the converter switch. The converter also includes a discharge circuit configured to discharge the bypass capacitor, wherein the discharge circuit includes an inductor. The inductor of the discharge circuit is magnetically coupled to the converter inductor.
