Abstract
A charging circuit includes first and second input terminals connecting the circuit to first and second supply terminals, respectively, of a DC power source, first and second output terminals providing an output voltage to a load to be charged, a first switch between the first and second input terminals, a current sensor between the first input terminal and the first output terminal in series with the first switch, a connecting element having first and second inductance connectors for connecting an inductance, the first inductance connector connected to the switch and the second inductance connector connected to the first output terminal, and a diode element connected to the first inductance connector and the second output terminal. The first switch and the current sensor are arranged to be connected to a control circuit arranged for controlling operation of the first switch in response to a signal received from the current sensor.
