Title:
POWER CIRCUIT AND POWER ADAPTER
Document Type and Number:
WIPO Patent Application WO/2023/207442
Kind Code:
A1
Abstract:
The present application provides a power circuit and a power adapter. The power circuit comprises a power input end, a power factor correction module, a DC-DC conversion module, and a power output end which are coupled in sequence. The power factor correction module comprises an input rectifier unit, a first inductor, a first diode, a first capacitor, a power switch transistor, and a variable resistance unit. According to the present application, the height of an overcurrent protection point can be adjusted, such that the problem that the over-current protection point is set too low to meet the full-power output of the power circuit is solved.
