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 1):
A DC-DC converter comprising:\n a capacitive power converter including an input portion, an output portion, a plurality of first capacitors, a plurality of switch elements, and a control circuit, the capacitive power converter outputting an output voltage to the output portion after performing a step-down conversion of an input voltage inputted to the input portion by switching the plurality of switch elements and charging and discharging the plurality of first capacitors; and an LC circuit disposed at the output portion and including an inductor and a second capacitor; wherein the capacitive power converter includes at least a first connection state and a second connection state depending on a connection state of the plurality of switch elements; and the control circuit controls switching of the plurality of switch elements, such that (i) in the first connection state, an operation is performed at a switching frequency equal to or higher than a first resonant frequency, the first resonant frequency being determined by a capacitance of the capacitive power converter and a capacitance and an inductance of the LC circuit, and (ii) in the second connection state, an operation is performed at a switching frequency equal to or higher than 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.
