Abstract

The invention discloses a power supply method, a power supply circuit and electronic equipment. The power supply circuit is connected with a rectification module in the electronic equipment. The electronic equipment has a working state and a standby state. The power supply circuit comprises a control module, a conversion module and a feedback module, wherein the control module is connected with the rectification module; the conversion module is connected with the control module and used for converting working voltage which is supplied by the rectification module into output voltage which can be used by at least one electrical module in the electronic equipment; the feedback module is connected with the control module; and when the electronic equipment is in the standby state, the feedback module generates a feedback signal and sends the feedback signal to the control module, and the control module controls the output power of the conversion module to be reduced on the basis of the feedback signal, so the power supply circuit enters a standby mode.

Description

technical field [0001] The present application relates to the field of power supply systems, in particular to a power supply method, a power supply circuit and electronic equipment. Background technique [0002] With the continuous development of science and technology, electronic technology has also developed rapidly, and there are more and more types of electronic products, and people have also enjoyed various conveniences brought by scientific development.
