Title:
POWER CONVERSION DEVICE AND POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/124141
Kind Code:
A1
Abstract:
A power conversion circuit 7A comprises a frequency modulation unit 12A that generates a voltage CLK in which pulse waves are superimposed on a voltage (VH-VL), and a booster unit 13A that receives the voltage CLK from the frequency modulation unit 12A and generates a voltage Vout that is higher than the voltage CLK using a charge pump operation. The booster unit 13A has capacitors C2, C3 that are charged by the voltage CLK, and, on the basis of the pulse waves included in the voltage CLK, switches between a first operation in which a charge is stored in the capacitors C2, C3 and a second operation in which a voltage based on the charge and the voltage CLK are superimposed for output.
