Title: CONTROL METHOD FOR CONTROLLING A POWER CONVERTER CIRCUIT AND RESPECTIVE POWER CONVERTER CIRCUIT
Abstract:
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 (Cout) 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 (te, tdis) of the releasing switch is adjusted by a closed-loop control of a compensation control variable (νaux) measured in the power converter circuit or of a characteristic value (vsample) derived from this compensation control variable (Vaux), and a respective power converter circuit.
