Electrical principle of traditional ignition system

The pulse igniter is essentially a high frequency oscillator. First, a high-frequency oscillator generates a high-frequency voltage. Secondly, the high-frequency voltage is increased to a large voltage of 15KV through a step-up transformer; Finally, the high-voltage discharge will produce electric sparks that will ignite combustible substances and produce flames. Pulse igniter can control its ignition and stop ignition by buttons, and the ignition rate is extremely high because it can generate electric spark by continuous discharge.

Extended data:

The electric pulse igniter is a device that ignites the combustible gas of the stove by using the electric spark of high-voltage discharge.

Pulse igniter is an electronic product that uses the pulse principle to generate electric spark to ignite combustible substances. Compared with the previous piezoelectric igniter, it has simpler operation and more reliable performance, and has been widely used in the ignition of various gas devices and industrial furnace fuels in the kitchen.

Pulse igniter mainly realizes the functions of safe ignition, flame detection, flameout protection, fault alarm and so on through the control system based on single chip microcomputer.

Pulse ignition circuit and flame detection circuit are added to the hardware to complete safe ignition and post-ignition detection. The success of ignition is determined by the feedback of the flame detection circuit. When the ignition is successful, the spark stops, and when the ignition fails, the valve is quickly cut off and closed, which avoids the gas leakage caused by the ignition failure and greatly improves the reliability of the product.
