    • 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.
    • 电源系统包括具有第一系统带宽(LB1)和第二开关模式电源(2)的第一开关模式电源(1)的并联布置,所述第一开关模式电源具有覆盖较高的第二系统带宽(LB2) 频率比第一个系统带宽(LB 1)。 第一开关模式电源(1)的尺寸设定为提供第一最大输出功率(P 1 m),第二开关模式电源(2)的尺寸被设计成提供小于第二最大输出功率(P 2 m)的第二最大输出功率 第一最大输出功率(P 1 m)。 控制电路(3)改变第一开关模式电源(1)和第二开关模式电源(2)两者的参考电压(Vr),以获得并联装置的输出电压(Vout)的相应变化 。
