In fact, the induction stove is an extremely simple device. Make a fully working prototype for even a novice radio amateur. Here is an excellent example for repetition: a simple scheme that does not contain in its composition neither microcircuits or kotrors. There are only two transistors and several other parts, allow you to build an induction slab with a heating power of 180 W.

Scheme of induction plate
The scheme is classic for the simplest induction heaters with self-excitation.
Coil plate
The radiating coil of the plate is a "snail" wound up to the turn of a thick insulated wire of 1.5 sq.mm. and consists of 18 turns with a tap from the middle. The turns are not dispelled, glued to adhesive strips.
Production of induction plates with their own hands
The board was made to order. You can assemble the scheme by mounting, or on a versatile board.
We set all the details on the fee from the youngest.
And ending with inductance.
Separate and cut output.
We solder feed wires, weekend transistors set to small radiators.
We connect the radiating coil to the output of the board.
Let's supply power from a powerful block. When installed on the coil of metallic dishes, the current consumed current will increase significantly.
After 10 minutes, water will boil.
The power consumed by the stove is 180 W, which is consumed from: 10 and consumption current at 18 V. This power has a higher efficiency compared to heating elements, as it is easily concentrated in the right place and is not spent on heat loss.
