Abstract
An economical centralized DC power consumption control system is used to separate electric power into an AC circuit for high-power-consumption electric appliances such as TV set, refrigerator, washing machine, and air conditioner and a DC circuit for low-power-consumption electric appliances such as lamp, electric fan, notebook computer, tablet computer, mobile phone, and digital camera. The DC circuit is equipped with multiple high-powered power supplies, each of which transforms commercial power to DC power, provides electricity to various low-power-consumption electric appliances, and directly links the electric appliances for supply of electric energy without individual rectifiers/transformers.
Claims13
A method of economical centralized DC power consumption control, comprising steps as follows:
- separating supplied electric power into an AC circuit for high-power-consumption electric appliances including TV set, refrigerator, washing machine and air conditioner and a DC circuit for low-power-consumption electric appliances including lamp, electric fan, notebook computer, tablet computer, mobile phone and digital camera;
- transforming commercial power to DC power via a high-powered power supply in said DC circuit, and providing electricity to all low-power-consumption electric appliances;
- restricting total power consumption of electric appliances activated simultaneously for energy saving as per modulated power of said power supply,
- wherein said DC circuit is used to modulate output voltage or current which matches running of an electric appliance for energy saving as per a distance between said power supply and said electric appliance.
An economical centralized DC power consumption control system separating supplied electric power into an AC circuit and a DC circuit,
- wherein said DC circuit is equipped with a high-powered power supply for all low-power-consumption electric appliances including lamp, electric fan, notebook computer, mobile phone and digital camera and provides common voltages to said electric appliances directly without requiring rectifiers/transformers,
- wherein said power supply contributes to less energy loss attributed to AC-to-DC transfer by modulating a distance between said power supply and said electric appliance.
