Abstract:
A switched-capacitor converter comprising:a supply voltage input for receiving a supply voltage; an output circuit comprising a load resistance and a load capacitance connected in parallel; a diode circuit comprising a first diode and a second diode connected in series at a diode junction point, said diode circuit being connected in parallel with said output circuit; first and second semiconductor switches connected in series at a switch junction point; said semiconductor switches being connected between said supply voltage input and said output circuit; and a flying capacitance connected between said switch junction point and said diode junction point; wherein said load capacitance is charged via said flying capacitance and said second diode when said first switch is ON and said second switch is OFF, and said load capacitance is discharged via said first diode and said flying capacitance when said first switch is OFF and said second switch is ON.
