Centralized DC power supply control system and method of economically controlling power consumption

摘要

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.

主权项

1. 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.
