Abstract:
A switched capacitor converter has a supply voltage input, an output circuit with one or more load capacitors, a semiconductor switch network. The switch network is connected at a switch junction point and across the voltage input, and has one or more pairs of said first and second switches. Each pair of switches is associated with one of the load capacitors and each pair is connected in series. The converter also has a charging capacitor network connected across the semiconductor switch network and across the voltage input. The charging capacitor network has one or more charging capacitors and inductances connected between the switch junction point and the output circuit. Each of the charging capacitors and inductances is associated with one of the load capacitors. The load capacitors are each charged by the associated charging capacitor when the associated first switch is closed and the associated second switch is open. And the load capacitors are each discharged by the associated inductance when the associated first switch is closed and the associated second switch is open.
