BLEEDER CIRCUIT CONTROL METHOD AND APPARATUS, BLEEDER DEVICE, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2023/061333

A1

Disclosed in the present application are a bleeder circuit control method and apparatus, a bleeder device, and an electronic device. The bleeder circuit comprises a first path and a second path; the first path is connected in parallel with the second path. The control method comprises: if it is detected that an input voltage of the bleeder circuit is reduced, controlling the first path to be turned on; otherwise, controlling the first path to be turned off, wherein when the first path is in an on state, the bleeder circuit is in a quick bleeding state, and when the first path is in an off state, the bleeder circuit is in a normal working state. When a power supply circuit is in a normal working state, the first path is controlled to be turned off, and at this moment, the bleeder circuit is in the normal working state, and voltage stabilization and interference signal elimination are achieved in the circuit; when the power supply circuit is in a bleeding state, the control module controls the first path to be turned on, so that the bleeding process of the power supply circuit is accelerated.
