Abstract

The voltage-sensing circuit structure is intended to avoid fast-scale subharmonic instabilities in switching power converters, comprising a compact circuit structure to be connected at the output of a switching power converter, by means of which the sensed feedback voltage is altered with a double transfer function so that concurrently the ripple component is amplified to obtain an enhanced fast- scale stability margin while attenuating the converter output voltage ripple in the power path.
