Electric heating system with direct-current power regulator

Abstract

The invention relates to an electric heating system with a direct-current power regulator. The electric heating system with the direct-current power regulator comprises an electric heating piece and is characterized in that the electric heating piece is connected with the direct-current power regulator, the direct-current power regulator comprises a step-down rectification regulating circuit and a central processing unit in communication with the step-down rectification power regulating circuit, the input end of the step-down rectification power regulating circuit is connected with a mains supply, and the output end of the step-down rectification power regulating circuit is connected with the electric heating piece. The electric heating system with the direct-current power regulator has the advantages that alternating current is converted into direct current, voltage is lowered, electricity using safety and personal safety are improved, electromagnetic radiation is avoided, meanwhile, a power regulating type working mode is adopted, energy utilizing efficiency is improved, and energy conservation and emission reduction are facilitated.

Description

technical field [0001] The invention relates to an electric heating system, in particular to an electric heating system provided with a DC power regulator. Background technique [0002] At present, all electric heaters are powered by AC220V voltage. There are problems: 1. When the insulation film of the electric heater is damaged, there will be a large leakage current, which is very harmful to human safety. 2. Products powered by AC220V have surface leakage current, which will cause the 30mA leakage protector to trip. 3. AC220V AC power supply, there is electromagnetic radiation, which is harmful to human body. [0003] Moreover, the current electric heaters are all working in constant power mode. The output power will not change with the change of time and temperature, so after the temperature reaches the temperature we set, there will be a lot of waste of energy consumption. Contents of the invention [0004] The purpose of the present invention is to solve the above ...
