Abstract

The invention relates to a novel energy-saving control circuit which is characterized by comprising a rectifying and filtering circuit (1), a switch power converting circuit (2), a voltage detecting and processing circuit (3), a load control circuit (4), a current detecting and processing circuit (5), a wireless remote circuit (6) and a main control unit (MCU); the input end of the rectifying and filtering circuit (1) is connected with an alternating current power supply, and the output end is respectively connected with the input ends of the switch power converting circuit (2) and the voltage detecting and processing circuit (3). By detecting and processing alternating input voltage and current, a load switch can be controlled and protected to work normally within a certain power range; by further detecting a voltage, load outputting can be cut off when the voltage of a grid fluctuates, so that electric equipment is protected; the load switch can be switched on in real time by wireless remote. The invention has the beneficial effects of simpleness, stable and reliable performance, easiness for realization and reasonable cost.

Description

Technical field: [0001] The invention relates to a novel energy-saving control circuit, which is especially suitable for the energy-saving circuit in household appliances. The invention belongs to the innovative technology in the field of electronic information application. Background technique: [0002] With the continuous improvement of residents' income, household appliances have become a necessary article for people's life, and have brought great convenience to people's life. The use of a large number of household appliances consumes more and more energy in standby, and the annual wasted electric energy is as high as 1.5 billion kWh. Therefore, the energy-saving potential of my country's household appliances is huge, and the energy-saving control of household appliances is imperative. [0003] At present, the power supply mode of resistance-capacitance step-down or transformer is commonly used in our white goods. The standby power consumption of household appliances wi...
