Abstract
(DE)
Die Erfindung betrifft ein Schaltnetzteil (400, 500, 600), mit: einem von einer Eingangsspannung (VIN) gespeisten Eingangsschaltkreis (401); einem mit dem Eingangsschaltkreis gekoppelten Ausgangsschaltkreis (402) zum Bereitstellen einer Ausgangsspannung (VOUT); und einemgalvanischen Trennelement (103) zwischen dem Eingangsschaltkreis(401) und dem Ausgangsschaltkreis (402), welches ausgebildet ist, eine vorgegebene Sicherheitsanforderung bezüglich einer Isolation zwischen der Eingangsspannung (VIN) und der Ausgangsspannung (VOUT) einzuhalten,wobei der Eingangsschaltkreis (401) zwei gekoppelte Tiefsetzerstufen (403) umfasst, von denen eine erste Tiefsetzerstufe (404) in der positiven Eingangsspannung (+VIN) und eine zweite Tiefsetzerstufe (405) in der negativen Eingangsspannung (-VIN) dem galvanischen Trennelement (103) vorgeschaltet sind.
(EN)
The invention relates to a switched-mode power supply (400, 500, 600), having: an input circuit (401) powered by an input voltage (VIN); an output circuit (402), coupled to the input circuit, for providing an output voltage (VOUT); and a DC isolating element (103) between the input circuit (401) and the output circuit (402), which isolating element is designed to observe a prescribed safety requirement in regard to isolation between the input voltage (VIN) and the output voltage (VOUT), wherein the input circuit (401) comprises two coupled step-down converter stages (403), of which a first step-down converter stage (404) in the positive input voltage (+VIN) and a second step-down converter stage (405) in the negative input voltage (-VIN) are connected upstream of the DC isolating element (103).
