Abstract
The invention relates to a circuit for converting AC voltage in DC voltage for one or two consumers (Rm, Ra), in which a first part of the current is led via a large induction coil (L50) and a first rectifier (Gm) and a second part of the current via a second rectifier (Ga) before the large induction coil in the input side. As a result of the division of the supplied current the induction coil (L50) can be dimensioned accordingly smaller for smoothing the output voltage and, despite this, the circuit can at the same time satisfy relevant standard specifications.
Claims9
A circuit for converting an AC voltage into an uncontrolled DC voltage for at least one consumer, comprising
- an AC power supply (W;T) having two external connections (EA)and at least two internal connections (IA),
- a rectifier module (Gm;G1) whose two inputs are connected to a respective internal connection of the AC power supply and which has two output lines with external connections for coupling at least one consumer (Rm;RL;R1) to them,
- at least an induction coil (L50;L1,L2) arranged in at least one of the connection lines between the internal connections of the AC power supply and the rectifier module (Gm),
- characterized in that at least a second rectifier module (Ga;
- G2) is available whose two inputs are connected to a respective internal connection of the AC voltage supply and which has two output lines for the connection of at least one consumer (Ra, RI;
- R2).
