What is the working principle of high-power induction cooker?

Rishiweiki commercial high-power induction cooker is a new type of stove (stove) in the commercial kitchenware market. It breaks the traditional open flame cooking method and adopts the heating principle of magnetic field induced current (also known as eddy current). The heat source of the induction cooker is generated by the electronic circuit board components to generate high-frequency current, and the rectifier circuit converts the 50 HZ / 60HZ alternating current into The DC voltage is converted into a high-frequency current with a frequency of 20-40KHz through the control circuit, and a high-frequency alternating magnetic field is formed through the spiral magnetic induction coil. When the magnetic field lines in the magnetic field pass through the metal vessel (magnetically conductive, also known as conductive Material) Alternating current (ie eddy current) is generated in the metal body of the heating part. The eddy current causes the iron molecules of the pot to move at a high speed and irregularly. To heat and cook food, so as to achieve the purpose of cooking. The thermal efficiency of electromagnetic heating technology is as high as 98%, which is 40% higher than traditional heating wire heating. It greatly saves energy and is widely used.
