Title:
VOLTAGE CONVERSION CIRCUIT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/077421
Kind Code:
A1
Abstract:
Provided in the present application is a voltage conversion circuit, comprising an inverter unit, a resonator unit, a transformer unit, and an output rectifier unit electrically connected in sequence. The inverter unit receives a first direct current voltage from a first voltage input end and invertedly converts the first voltage into a first alternating current voltage. The inverter unit comprises a first branch and a second branch. The first branch and the second branch are connected in parallel between a high voltage end and a low voltage end of the first voltage input end. The first branch comprises a first inverted output end. The second branch comprises a second inverted output end. The first and second inverted output ends together output the first alternating current voltage. The first branch receives a frequency-adjustable control signal. The second branch receives a duty cycle-adjustable control signal. The resonator unit, the inverter unit, and the output rectifier unit together constitute a resonant cavity to form a resonant circuit so as to convert the first alternating current voltage into a second direct current voltage. Also provided in the embodiments of the present application is an electronic device comprising the voltage conversion circuit described above.
