Abstract

According to the invention, a current measurement circuit for providing a measurement signal for a controller for controlling a switching of power switches of a power converter comprises a first current sensing circuit for sensing a first bidirectional current representative of a current through a first power switch of the power converter. The first current sensing circuit is being adapted to provide a first sensing signal indicative of the first bidirectional current. The current measurement circuit further comprises a second current sensing circuit for sensing a second bidirectional current representative of a current through a second power switch of the power converter. The second current sensing circuit is adapted to provide a second sensing signal indicative of the second bidirectional current.
