Title:
DC POWER SUPPLY SYSTEM AND ELECTRIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/008904
Kind Code:
A1
Abstract:
A DC power supply system according to the present invention suppresses an arc which is generated when, for example, an input plug is disconnected from an outlet during power supply, and enables, a commercially available electric apparatus to which an alternating current is inputted, to be connected to an outlet. A DC source 11 supplies a DC voltage Vin to a DC power supply line 20. A voltage conversion unit 100 converts the DC voltage Vin supplied to the DC power supply line 20 into a voltage Vout having a waveform in which a low-level potential for a first predetermined time and a high-level potential for a second predetermined time repeatedly appear. An outlet 110 outputs the voltage Vout obtained by conversion of the voltage conversion unit 100.
