Problems solved by technology
At present, the state mandates that the standby power consumption of electrical appliances is less than 0.5W. Even if the electrical appliances are not in use, they will be in a standby state as long as they are connected to the power supply, and will consume electricity. Therefore, even if the standby power consumption of each electrical appliance is less than 0.5W, If many electrical appliances are in the standby state every day, it will also consume a lot of energy, and the standby power consumption will be large, resulting in energy waste

The invention discloses a standby power supply management circuit which comprises a power supply interface, a voltage reduction rectifying module, a power supply composite module, a silicon controlled rectifier, an infrared signal receiving module, a silicon controlled triggering module, a power supply module, a main controller and keys, wherein the power supply composite module is used for compounding first direct-current voltage output from the voltage reduction rectifying module and second direct-current voltage output from the power supply module so as to output fourth direct-current voltage to supply power to the infrared signal receiving module, the silicon controlled triggering module and the silicon controlled rectifier; the infrared signal receiving module is used for outputting a pulse signal when receiving an infrared signal; the main controller is used for confirming a remote control instruction corresponding to the infrared signal according to the pulse signal, or used for outputting a corresponding control signal to the silicon controlled triggering module according to the states of the keys; the silicon controlled triggering module is used for controlling the silicon controlled rectifier to be powered on or off according to the control signal, so as to control whether the power supply module is communicated with an alternative-current power supply or not.
Description
technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a standby power management circuit and electronic appliances. Background technique [0002] When users are not using electronic appliances, they are usually not used to shutting off the electrical appliances and then cutting off the power supply, so many electrical appliances are still connected to the power supply and still have power consumption when users are not using them. At present, the state mandates that the standby power consumption of electrical appliances is less than 0.5W. Even if the electrical appliances are not in use, they will be in a standby state as long as they are connected to the power supply, and will consume electricity. Therefore, even if the standby power consumption of each electrical appliance is less than 0.5W, If many electrical appliances are in the standby state every day, it will also consume a lot of energy, and the standby power con...
