Document Type and Number:
WIPO Patent Application WO/2023/151376
Kind Code:
A1
Abstract:
An electric spark elimination circuit, a power adapter, and an electronic device. The electric spark elimination circuit (100) comprises: a change-over switch (S), a first end of the change-over switch (S) being connected to an output end of a direct-current power supply, and a second end of the change-over switch (S) being connected to a load; and a detection control module (110), the detection control module (110) being respectively connected to a third end of the change-over switch (S), a control end of the change-over switch (S) and an output end of the direct-current power supply, and the detection control module (110) being used for detecting a current at the output end of the direct-current power supply, controlling the first end and the second end of the change-over switch (S) to be communicated with each other when a current is detected, and controlling the second end and the third end of the change-over switch (S) to be communicated with each other when no current is detected.
