Abstract:
An inductorless DC to DC converter comprises an input for connection to a DC supply and an output for connection to a DC load. A first capacitor is connected across one of the input and the output. A plurality of second capacitors are connected in series across the other of the input and the output. The first capacitor and the second capacitors are of equal capacitance. A plurality of switch circuits are provided, one for each second capacitor. Each switch circuit is connected across the first capacitor and one of the second capacitors. A control circuit controls operation of the plurality of switch circuits to momentarily place each second capacitor alternately across the first capacitor to transfer voltage therebetween to selectively step-down or step-up voltage of the DC supply to the DC load.

Claim (Index 6):
A buck-boost DC TO DC converter, comprising:\n an input for connection to one of a DC supply and a DC load and an output for connection to the other of the DC load and the DC supply; a first capacitor connected across the output; a plurality of second capacitors connected in series across the input; a plurality of bidirectional switch circuits, one for each second capacitor, each bidirectional switch circuit is connected across the first capacitor and one of the second capacitors; and a control circuit controlling operation of the plurality of bidirectional switch circuits to momentarily place each second capacitor across the first capacitor to transfer voltage therebetween so that sharing of voltage across each second capacitor is equal to step-up or step-down voltage of the input to the output in an amount corresponding to the number of second capacitors.
