CONVERTER CIRCUIT WITH FORWARD AND BACKWARD CONTROL

摘要

The present invention relates to a converter circuit and a conversion method for converting an input signal of a first value to an output signal of a second value based on a switched operating mode, wherein an output feedback loop (40) and an additional input forward control loop (60) are provided. The additional input forward control loop (60) serves to correctly control a switching parameter not only with respect to the output load but also over a wide input voltage range. This leads to an improved power efficiency and reliability of the converter circuit.
