Abstract

The invention relates to a resistive and capacitive voltage reducing device which comprises a control module and a power supply module connected with the control module. The power supply module comprises a resistive and capacitive voltage reducing unit and a second voltage reducing unit, the resistive and capacitive voltage reducing unit comprises a first capacitor, and the second voltage reducing unit comprises a second capacitor and a controlled switch. The second capacitor is connected with the first capacitor in parallel through the controlled switch, the resistive and capacitive voltage reducing unit supplies power to the control module after carrying out voltage reducing to an input first alternating voltage, and the control module regulates the power supply current size of a system under different statuses by controlling the switching on and the switching off of the controlled switch. The application of the resistive and capacitive voltage reducing device has the advantages that cost is low, stand-by power consumption meets the instruction requirements of energy using products (EPUs), and energy is saved.

Description

technical field [0001] The invention relates to the field of electronic equipment, and more specifically, to a resistance-capacitance step-down device. Background technique [0002] As the EUP (Energy-using Products, energy-consuming products) directive's restriction date is approaching, many products exported to Europe must meet the requirements of the EU's EUP directive, which puts higher demands on electronic product developers Requirements; especially for home appliances, because they are sensitive to cost, the requirements are stricter, but they must meet the requirements of the EUP directive, so the design requirements for the technical solutions of home appliances are relatively high. [0003] Usually, for products that are not too sensitive to cost, have less strict requirements on them and have relatively large current consumption, most of them may choose switching power supply, but the cost of switching power supply is high, and the requirements for EMC are relativ...
