Abstract: A circuit arrangement for switched boundary mode power conversion, a corresponding signal processor and a method of switched boundary mode power conversion are provided. The circuit arrangement comprises an input for receiving an input voltage from a power supply, an output to provide an output voltage to a load, an energy storage device, a controllable switching device, and a signal processor. The signal processor is connected to the controllable switching device and being configured for zero-current switching of the switching device, wherein the signal processor is further configured to determine at least one switching point for the zero-current switching from a first voltage signal and a second voltage signal, wherein the first voltage signal corresponds to the input voltage and the second voltage signal corresponds to the output voltage.
