The induction cooker is a kitchen appliance that converts electrical energy into heat by using the principle of electromagnetic induction. Inside the electromagnetic cooker, the alternating current of 220V50Hz/60Hz is converted into pulsating direct current by the rectifier circuit, and the alternating current is converted into a high frequency alternating current of 20Hz~~30Hz by direct current. High frequency alternating electromagnetic field (eddy current) is generated by the induction coil. When the magnetic force lines pass through the bottom of the pot, numerous small eddy currents are generated. When the eddy current overcomes the internal resistance of the pot body, the electric energy is converted to thermal energy, and the generated heat is the heat source of cooking, so that the pot body itself is heated at a high speed to meet the needs of the user. . phone case custom,phone case designs,phone case decorations,business phone case Dongguan Yingxin Technology Co., Ltd. , https://www.yingxinelectronic.com
