SWITCHED-MODE POWER SUPPLY WITH REGULATION OF LINE CURRENT CONSUMPTION

摘要

The invention relates to a switched-mode power supply with a power regulating device regulating the consumption of a line current, and a rectifier connected to said power regulating device (LRA), provided with output terminals and an available bus voltage (VBUS). A switched mode regulator (SCH) is connected to the output terminals of the rectifier (GLA). An output voltage (VOUT) can be tapped from the output terminals of said switch-mode regulator (SCH). Both the bus voltage (VBUS) and the output voltage (VOUT) are backcoupled to the power regulating device (LRA) by means of feedback branches (RZ1, RZ2).
