Problems solved by technology

In traditional technology, the power supply continuously outputs the maximum power that the control system may need regardless of the actual working conditions of the control system, which causes the power supply circuit to consume a large amount of power most of the time
Currently, some switching power supplies have improved somewhat in this regard, but the cost of such a system is still high

Abstract

A power saving system for a household electric appliance includes a signal processing unit, a step down network having an adjustable impedance for stepping down an input voltage, and an impedance control switch electrically connected with the step down network and configured for controlling the impedance of the step down network. The signal processing unit is electrically connected to impedance control switch and configured to monitor the working condition of the household electric appliance, calculate the current demanded by the household electric appliance at a next moment, and transmit a signal to the impedance control switch so as to control the impedance control switch to adjust the impedance of the step down network according to the calculation.

Description

technical field [0001] The present invention relates to the power management technology of household appliances, and more particularly, to a microprocessor-based control system for saving the power consumption of household appliances. Background technique [0002] Home appliances with electronic control systems usually require stable DC power. The DC power supply is usually converted directly from the AC power supply by a power conversion device, such as a low frequency linear transformer, a switched mode power supply or a simple step-down circuit. The electronic control system may require different power under different working conditions, and the power supply should always be able to provide enough power for the control system so that the electronic control system can work normally. In traditional technology, the power supply continuously outputs the maximum power that the control system may require, regardless of the actual operating conditions of the control system, whi...
