Abstract

The invention discloses a single-live-wire electricity taking circuit, which relates to the technical field of switch equipment. The single-live-wire electricity taking circuit comprises a light-off electricity taking circuit, a light-on electricity taking circuit, a constant-current charging circuit and a power-off electric quantity holding circuit. The constant-current charging circuit comprises a first power supply voltage stabilizer, a second power supply voltage stabilizer, a light-on and light-off switching constant-current charging circuit and a light-on constant-current charging circuit. The output end of the light-off electricity taking circuit, the input end of the first power supply voltage stabilizer and the control end of the light-on and light-off switching constant-current charging circuit are connected, and the output end of the first power supply voltage stabilizer is electrically connected with the input end of the second power supply voltage stabilizer and the input end of the light-on constant-current charging circuit. The output end of the second power supply voltage stabilizer, the output end of the light-on constant-current charging circuit and the input end of the power-off electric quantity holding circuit are electrically connected; by means of the light-off electricity taking circuit, the light-on electricity taking circuit, the constant-current charging circuit, the power-off electric quantity holding circuit and the like, a lamp is not prone to flicker in the application of the single-live-wire electricity taking circuit.

Description

technical field [0001] The invention relates to the technical field of switchgear, in particular to a single live wire power-taking circuit. Background technique [0002] At present, the smart switch based on the single live wire technology has matured and improved a lot compared to many years ago, but there are still some problems. [0003] The compatibility with lamp loads is low, and low-power lamps are prone to flicker. [0004] When the light is turned on, the self-heating is relatively large. [0005] The power supply efficiency is low, or there is insufficient power supply, which cannot effectively cope with the sudden demand for large current of the NB-IoT network. [0006] Existing technical problems and thinking: [0007] How to solve the technical problem that lamps are prone to flicker in the application of single live wire power-taking circuit. Contents of the invention [0008] The technical problem to be solved by the present invention is to provide a si...
