Abstract:
A DC-DC converter includes a capacitive power converter connected to a first terminal side, an LC circuit connected to a second terminal side and including an inductor and a second capacitor, and a control circuit that performs switching of a plurality of switch elements. The control circuit performs the switching at a switching frequency equal to or higher than a resonant frequency determined by the capacitance of the capacitive power converter and the capacitance and the inductance of the LC circuit, steps down an input DC voltage inputted to the first terminal, and outputs an output DC voltage from the second terminal.

Claim (Index 3):
A DC-DC converter comprising:\n a capacitive power converter including a plurality of first capacitors, a plurality of switch elements, and a control circuit that controls switching of the plurality of switch elements, the capacitive power converter stepping up or stepping down a voltage by switching the plurality of switch elements and charging and discharging the plurality of first capacitors; and an LC circuit including an inductor and a second capacitor, the inductor including one end portion and another end portion, the one end portion being connected to the capacitive power converter, the another end portion being connected to the second capacitor; wherein the capacitive power converter includes at least a first connection state and a second connection state for electric power conversion, the capacitive power converter being controlled by the control circuit so as to convert an input voltage to an output voltage; in the first connection state, a time of the first connection state is shorter than one-half of a reciprocal of a first resonant frequency, the first resonant frequency being determined by a capacitance of the capacitive power converter and a capacitance and the inductance of the LC circuit; and in the second connection state, a time of the second connection state is shorter than one-half of a reciprocal of a second resonant frequency, the second resonant frequency being determined by the capacitance of the capacitive power converter and the capacitance and the inductance of the LC circuit.
