Beschreibung
Zusammenfassung:	The invention refers to a control method for controlling a power converter circuit, said power converter circuit comprising at least one inductive element (L) storing an output energy, a charging switch (C) for charging the inductive element (L), a releasing switch (R) for releasing the stored output energy from the inductive element (L) and for charging the inductive element (L) with a compensation energy and an output capacitor (C out ) saving the released output energy, wherein the compensation energy is used to achieve Minimized Voltage Switching (MVS) condition when switching on the charging switch (C), wherein a turn on time (t e , t dis ) of the releasing switch is adjusted by a closed-loop control of a compensation control variable (v aux ) measured in the power converter circuit or of a characteristic value (v sample ) derived from this compensation control variable (v aux ), and a respective power converter circuit.
