Abstract

An energy management circuit and energy management method for the sleep-wake mode of electrical appliances, the circuit includes a rectification circuit of a power supply, a DC boost circuit, a low-dropout linear voltage regulator and an electrical appliance, in the rectification circuit, DC A supercapacitor, a timer circuit, a switch circuit and a reset circuit are arranged after the boost circuit. The timing circuit controls the sleep time of the electrical appliance (chip), the switch circuit is used as an enabling signal for the power supply energy to flow in, the reset circuit is connected to the subsequent electrical appliance (chip), and receives an end signal of work completion, etc. The user can choose the specific sleep time according to the actual needs to achieve a balance between power saving and normal work.

Description

technical field [0001] The invention relates to a power supply and an electrical appliance, in particular to an energy management circuit and an energy management method for a sleep-wake mode of an electrical appliance. Users can select a specific sleep time according to actual needs to achieve a balance between power saving and normal operation. Background technique [0002] The current mainstream chip energy management method is to process the power supply energy through simple rectification, boosting, etc., and obtain a relatively stable voltage through a low-dropout linear regulator for subsequent electrical appliances (chips). For example [Y.-J.Huang, T.-H.Tzeng, T.-W.Lin, C.-W.Huang, P.-W.Yen, P.-H.Kuo, C.-T. Lin, and S.-S.Lu, "A Self-Powered CMOS Reconfigurable Multi-Sensor SoC for Biomedical Applications," IEEE J. Solid-State Circuits, vol.49, no.4, pp.851–866, Apr.2014 .], the energy management is mainly composed of a rectifier circuit and a DC boost circuit, and a...
