How to connect the energy storage coil of the induction cooker

How does an induction cooker function?

An induction cooker works by using a copper coil placed underneath a cooking utensil. The important design parameters of the coil include geometry size, number of turns, and distribution of the iron cores.

How does coil design affect induction cooker efficiency?

The coil design substantially affects the induction cooker efficiency that is dependent on the compatibility of the cooking utensil with the induction heating electromagnetic waves. The important design parameters of the coil include geometry size, number of turns, and distribution of the iron cores.

What is a typical induction cooker coil?

A typical induction cooker coil, as shown in Fig. 1, consists of a spiral copper wire with a diameter of 3.8–4.2 mm. It is placed under the cooking vessel, with the inner diameter of the coil matching the inner diameter of the pan. The number of coil turns is calculated based on the power requirement.

Why is coil inductance important?

Coil inductance is an important technical parameter in the induction cooker system. It mainly depends on the coil geometry size, the number of coil turns, and the distribution of the iron cores located a short distance away from the coil.

What is the drive section of an induction cooker?

The drive section regulates the amount of electrical current sent to the induction coil, allowing for more efficient heat generation and transfer. The controller includes a number of sensors that monitor temperature, adjust power output, and detect any malfunctions with the induction cooker.

What is the value of the coil inductance?

The value of the coil inductance is usually in the scope of 0.3 and 0.5. For the induction cooker coil described in Table 1, the value of the coil inductance is given in Figure 4.
