Title:
POWER SUPPLY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/190117
Kind Code:
A1
Abstract:
Provided is a power supply control device making the vicinity of the peak of a voltage value as flat as possible and using an ultra-small switching circuit that makes contact and contactless power feeding possible. The power supply control device is provided with: a rectifier diode 3 for converting an AC power to a DC power; an inverter circuit 4 operating at high frequency with the DC power; a primary side transformer 5 connected to the inverter circuit 4; a secondary side high-frequency transformer 6 magnetically coupled with the primary side transformer 5; and a rectifier 8 for converting the AC power converted to voltage by the secondary side high-frequency transformer 6 to a DC power. The inverter circuit 4 has a plurality of switching elements which are connected in series to divide an input voltage. Each of the switching elements has a harmonic resonant circuit and has a control means for controlling a voltage peak value of each of the switching elements.
