Abstract
A dual stage power converter and a method for charging an energy storage device are presented. The dual stage power converter has a first stage and a second stage arranged in series. A first stage has a voltage divider circuit with a flying capacitor to convert an input voltage at an input of the dual stage power converter into a smaller, intermediate voltage at an intermediate node of the dual stage power converter. A second stage has a voltage regulator circuit to receive said intermediate voltage for regulating, using a feedback loop, an output voltage at an output of the dual stage power converter. The described dual stage power converter enables a reduction of the switching power losses in the voltage regulator circuit and a reduction of the resistive power losses within an external cable connecting the dual stage power converter with an external wall adapter.
