Abstract:
The invention relates to an electric circuit arrangement for the input protection circuit of a switching power supply, having a surge protection circuit, which is contacted with a supply voltage on an input side and to which a current-compensated choke is connected as a suppression component, said current-compensated choke being connected to a rectifier circuit comprising an energy storage means on an output side. Via modifications to the circuit technology, such as using two varistors as surge protections, and by using suitable switching elements, such as silicon diodes as rectifier elements and ceramic capacitors as an energy storage means, the input protection circuit is designed such that the requirements, which an expanded input voltage range demands of a surge circuit, are fulfilled. Furthermore, the invention relates to a switching power supply having an electric circuit arrangement according to the invention for the input protection circuit.

Claim (Index 1):
An electric circuit arrangement ( 30 ) for the input protection circuit of a switching power supply, having a surge protection circuit ( 12 ), which is contacted with a supply voltage on an input side and to which a current-compensated choke is connected as a suppression component ( 14 ), said current-compensated choke being connected to a rectifier circuit ( 16 ) comprising an energy storage means ( 18 ) on an output side,\n characterized in that the surge protection circuit ( 12 ) is formed by a first and a second varistor (RV 100 , RV 101 ), said first varistor (RV 100 ) being arranged upstream of the current-compensated choke (LD 100 ) and said second varistor (RV 101 ) being arranged downstream of the current-compensated choke (LD 100 ), in that the current-compensated choke (LD 100 ) is dimensioned such that it has a smallest possible ohmic resistance and a largest possible inductivity, in that the rectifier circuit ( 16 ) comprises silicon diodes (D 100  to D 104 ) having an average forward current of at least 5 Amperes, in that the energy storage means ( 18 ) is realized as a ceramic capacitor (CK 100 , CK 102 ), and in that conducting path fuses covered by a casting compound are integrated in a conductor plate as surge protection devices.
