Abstract
A power converter comprises an inductor (LP) and a controllable switch (CF) coupled to the inductor. A switch controller () supplies a periodic switching signal (VC) which has a repetition time and a duty cycle to the controllable switch (CF) to generate a periodical inductor current (IL) through the inductor. A generator () generates an emulated signal (IE) based on timing information (TI) which represents the repetition time and the duty cycle to emulate a current signal being representative of the inductor current. A comparator () compares the emulated signal (IE) with the current signal (CS) to obtain an error signal (E). A generator controller () receives the error signal (E) to supply a control signal (VD) to the generator () to adapt a property of the emulated signal (IE) to become substantially equal to a property of the current signal (CS).
