Abstract

The invention discloses a power switching circuit, a power switching method, a wire controller and air conditioning equipment. The circuit comprises a Homebus power supply module and a battery module,and one of the Homebus power supply module and the battery module is selectively conducted with a wire controller through a power supply switching module to supply power to the wire controller; one end of the power supply switching module is connected with the Homebus power supply module and the battery module, the other end of the power supply switching module is connected with the wire controller, and the power supply switching module is used for controlling the battery module to be conducted with the wire controller when the first current and the second current meet preset conditions; andwhen the first current and the second current do not meet the preset condition, the Homebus power supply module is controlled to be connected with the wire controller, wherein the Homebus power supplymodule outputs the first current, and the battery module outputs the second current. According to the invention, the wire controller can be prevented from stopping working due to insufficient power supply, and the stability is improved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a power switching circuit, a power switching method, a wire controller and an air conditioner. Background technique [0002] With the development of the economy, customers have higher and higher requirements for the intelligence of home appliances, and more and more functional requirements, resulting in more and more power consumption of products. At present, the wire controller is powered by the Homebus power supply module of the internal unit, and the power provided is limited. When the power required by the wire controller is greater than the power provided by the Homebus power supply module, the wire controller resets and cannot be used normally. [0003] Aiming at the problem in the prior art that the insufficient power provided by the Homebus power supply module causes the wire controller to reset and cannot be used normally, no effective solution has been propo...
