Abstract

The invention relates to a starting circuit and a control method thereof. The circuit comprises a power supply circuit used for outputting a power supply voltage; the power supply control circuit is electrically connected with the power supply circuit; the power supply conversion circuit receives the power supply voltage and outputs a first output voltage and a second output voltage through a first secondary winding and a second secondary winding respectively; the intelligent control module receives the second output voltage and outputs a judgment signal according to an instruction signal; the dummy load is electrically connected with the first secondary winding; the dummy load control circuit is electrically connected with the dummy load, and the dummy load control circuit receives the judgment signal to control the on-off of the dummy load; the voltage negative feedback circuit detects the first output voltage and feeds back the first output voltage to the power supply control circuit so as to control the first output voltage and the second output voltage. On-off of the dummy load is controlled through the dummy load control circuit, the first output voltage is detected through the voltage negative feedback circuit for feedback, and the purposes of standby low power consumption and quick start are achieved.

Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to a starting circuit and a control method thereof. Background technique [0002] With the emergence and development of smart products, the requirements for fast response of the smart products are getting higher and higher. In the prior art, the smart products will generate a large standby power consumption while achieving faster startup speed. [0003] At present, no effective solution has been proposed for the problem of coordination between high response and low power consumption in related technologies. Contents of the invention [0004] In view of the above problems, the present invention provides a starting circuit and a control method thereof. [0005] In the first aspect, the embodiment of the present application proposes a startup circuit, including: [0006] a power supply circuit, configured to output a power supply voltage; [0007] The power supp...
