Abstract

A converter circuit arrangement and a method for operating a converter circuit arrangement are disclosed. In an embodiment an arrangement includes a switched-mode input converter sub-stage comprising a step-up converter configured to convert a rectified input voltage on an input side into an intermediate voltage higher than the rectified input voltage, a switched-mode output converter sub-stage configured to convert the intermediate voltage into a direct output voltage at an output side, a switch configured to switch both the switched-mode input converter sub-stage and the switched-mode output converter sub-stage and a control circuit configured to control the switched-mode output converter sub-stage to a power demand at the output side independent of the switched-mode input converter sub-stage by operating the switch with a controlled duty cycle, wherein the control circuit is connected to the switched-mode output converter sub-stage and the output side and configured to apply a first control parameter based on a sensed output voltage and/or a sensed output current and to apply a second control parameter based on a sensed current and/or a sensed voltage of the switched-mode output converter sub-stage.
