Patent ID: 7696735

Claim:
A switched capacitor converter comprising: an output circuit comprising a load capacitance, wherein said output circuit comprises a plurality of load capacitors; a semiconductor switch network connected at a switch junction point; said network being connected across a voltage input, wherein said semiconductor switch network comprises a plurality of pairs of said first and second switches, each pair associated with one of said load capacitors; and a charging capacitor network connected across said semiconductor switch network and across said voltage input, and comprising a charging capacitance and an inductance connected between said switch junction point and said output circuit, wherein said charging capacitor network comprises a plurality of charging capacitors each associated with one of said load capacitors; wherein said load capacitance is charged by said charging capacitance when a first switch of said semiconductor switch network is closed and a second switch of said semiconductor switch network is open, said load capacitance is discharged by said inductance when said first switch is closed and said second switch is open, and each of said load capacitors is charged by said associated charging capacitors when said associated first switch is closed and said associated second switch is open.
