Title:
POWER SUPPLY AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/139131
Kind Code:
A1
Abstract:
[Problem] To provide a power supply circuit, the potential difference variation of which is small. [Solution] A power supply circuit of the present invention includes: a first demultiplexing unit 5 for separating an AC voltage; a first full-wave rectifier circuit 9 for rectifying a first seperated voltage 7 seperated by the first demultiplexing unit 5; a first phase shifter 13 for shifting the phase of a second seperated voltage 11 seperated by the first demultiplexing unit 5; a second full-wave rectifier circuit 15 for rectifying the output voltage from the first phase shifter 13; a first multiplexing unit 17 for combining the output voltage of the first full-wave rectifier circuit 9 and the output voltage of the second full-wave rectifier circuit 15; a second demultiplexing unit 21 for separating the output voltage from the first multiplexing unit 17; a second phase shifter 25 for shifting the phase of a third seperated voltage 23 seperated by the second demultiplexing unit 21; and a second multiplexing unit 29 for combining a fourth seperated voltage 27 seperated by the second demultiplexing unit 21 and the output voltage from the second phase shifter 25. The phase variations by the first phase shifter 13 and the second phase shifter 25 are different from each other.
