The Role of Transformers

2018-12-28

The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer) and so on.

It can be divided into power transformer and special transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, mine transformer, audio transformer, medium frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, transformer, etc.).

Electromagnetic oven is an electric cooking utensil based on the principle of electromagnetic induction heating. It is composed of high frequency induction heating coil (excitation coil), high frequency power conversion device, controller and ferromagnetic cooker.

A high frequency transformer is composed of the inner heating coil disc of the pot and the electromagnetic furnace. The inner coil is the primary transformer and the secondary one is the pot. When the internal primary heating coil disc has alternating voltage output, the induction current will inevitably be generated on the secondary cooker body. The induction current will heat through the resistance of the cooker body itself (so the cooker itself is also a load) to generate heat.
