Glass Plate:

Let us start with the glass plate. This part is the top surface of the induction cooker which generally is made of
glass. The button or touch control signs and text are printed on it. The glass plate is what makes the induction
cooker easy to clean and looks sleek.
LED Display and PCB:
A light-emitting diode display (LED Display) of an induction cooker is a panel display that produces light when there
is a current flow in it. It allows the user to regulate the induction cooker through its control panel that is connected
to the PCB. There are induction cookers that have button control and others have touch control.
The Printed Circuit Board or the PCB is the one that processes the functions asked by the user. It works as the
brain of the induction cooker. The PCB itself has various small components. Part of it is the led driver which is
attached to the back of the panel display and is linked to the PCB. All other small parts functions are as essential
as the major parts.
Power Supply:
The power supply of an induction hob is the device that supplies electrical power to the hob by converting the
electric current to the right voltage and frequency. The power supply has input and output connections; the power
input receives the current from an electric power source while the output sends the current to the electrical load.

The power supply of an induction cooker is very specific with its power range, such as the voltage and frequency.
With this, the power range of the power supply must be compatible with the power source wherein the standard
range is between 220 V to 240 V with 50 to 60 frequencies.

Fan:
The fan functions as the cooling system of the induction cooker. It balances the heat when it is too hot. It also
makes the heat residues dissipate after its usage. The details of the fan depend on the hob’s interior structure.

Coil
The coil is the unique component of the induction cookers. It is the key to creating a magnetic field, with the electric
field, that transfers to the cookware.
Through induction, the electrical energy is transferred to the cookware from the coil. The coil is attached below
the induction panel. In the center of it is the temperature sensor, which also has two temperature components.

Bottom Cover:
Most of the bottom covers are made of plastic, but others are metal and crystal plates. This is used to protect the
internal structure of the induction cooker and to form the external design.
