ABSTRACT:
A power supply system comprises a parallel arrangement of a first switched mode power supply (1) which has a first system bandwidth (LB1) and a second switched mode power supply (2) which has a second system bandwidth (LB2) covering higher frequencies than the first system bandwidth (LB1). The first switched mode power supply (1) is dimensioned to supply a first maximal output power (P1m), the second switched mode power supply (2) is dimensioned to supply a second maximal output power (P2m) being smaller than the first maximal output power (P1m). A control circuit (3) varies a reference voltage (Vr) of both the first switched mode power supply (1) and the second switched mode power supply (2) to obtain a corresponding variation of an output voltage (Vout) of the parallel arrangement.
