Abstract:
1. A control unit (μC′) comprising a current simulator (CS′) configured for simulating a slope (dI L(on) /dt) of an inductor current (I L(on) )which flows through a storage inductor (L) placed in an inductive branch of a DC-to-DC voltage converter circuit (VCC′) which is being operated in a discontinuous current mode, said inductor current (I L(on) ) being such that the flowing occurs in each cyclically recurrent on-state phase of a first semiconductor switch (S) during which said storage inductor (L) is connected to a DC input voltage (U in ) of the DC-to-DC voltage converter circuit (VCC′), said current simulator (CS′) being configured for charging, based on the simulated slope (dI said control unit (μC′) being configured for using the detected rise time in setting, equal to said detected rise time, a duration of said on-state phase, to thereby control functionality of said DC-to-DC voltage converter circuit (VCC′).
