Title:
DC-DC CONVERTER
Document Type and Number:
WIPO Patent Application WO/2018/066444
Kind Code:
A1
Abstract:
A DC-DC converter (1) is provided with: a capacitive power converter (10) connected to the side of a first terminal (101); an LC circuit (20), which has an inductor (L10) and a second capacitor (C20), and which is connected to the side of a second terminal (201); and a control circuit (17) for switching a plurality of switch elements. The control circuit (17) performs the switching at a switching frequency equal to or higher than a resonance frequency specified by the capacitance of the capacitive power converter (10), and the capacitance and inductance of the LC circuit (20), reduces a direct current voltage (Vin) inputted to the first terminal (101), and outputs the voltage as a direct current voltage (Vout) from the second terminal (201).
