Abstract
A power supply system comprises a parallel arrangement of a first switched mode power supply () which has a first system bandwidth (LB) and a second switched mode power supply () which has a second system bandwidth (LB) covering higher frequencies than the first system bandwidth (LB). The first switched mode power supply () is dimensioned to supply a first maximal output power (P), the second switched mode power supply () is dimensioned to supply a second maximal output power (P) being smaller than the first maximal output power (P). A control circuit () varies a reference voltage (Vr) of both the first switched mode power supply () and the second switched mode power supply () to obtain a corresponding variation of an output voltage (Vout) of the parallel arrangement.
