Silicone rubber fiberglass sleeving has the following advantages:ġ. Wire material: Silicone rubber fiberglass sleeving Pulse voltage of more than ten thousand volts is induced at L5, which breaks down the gap between discharge electrodes and produces discharge sparks.The terminal is inserted on the pulse, the function is to receive the electrons emitted by the pulse.Various quick-connect terminals provide 2.8mm x 0.8 mm or 2.8mm x 0.5mm and 4.8 mm x 0.8 mm. The energy stored in C3 is quickly discharged. Capacitor C2 discharges to the trigger electrode of thyristor through VD2 to make SCR of thyristor turn on. When the voltage of C2 is charged to the on voltage of trigger diode VD2, VD2 is broken down. R2, C2, VD2, SCR, C3, L4 and L5 constitute charge discharge circuit and ignition circuit.
Before C2 voltage is charged to the on voltage of trigger tube VD2 (about 30V), C3 has no discharge circuit, and the voltage is higher and higher. Only when the current in L2 decreases from the maximum value, the induced electromotive force of 元 makes VD1 on, and charges C3 through L4, and charges C2 through R2. According to the connection method of each winding in T1, when L2 is in the current increasing stage, the direction of induced electromotive force in 元 makes VD1 unable to conduct. After the magnetic energy consumption in L2 is completed, the base potential of VT decreases again, which makes VT turn on again and enter a new oscillation period.ĭiodes VD1, C3 and L4 constitute a high voltage rectifying energy storage circuit. When the polarity of the induced electromotive force in L1 changes, VD1 starts to turn on, and the energy of L2 is transferred to 元. As a result, VT enters the cut-off state quickly.
The collector current begins to decrease, and the polarity of the induced electromotive force in L1 changes, which further reduces the base current, thus forming a positive feedback process. As a result, the VT quickly enters the saturation state, and the collector current of VT is in saturated state Therefore, the induced electromotive force in L1 will decrease, the base current of VT will also decrease, and VT will exit the saturation region. This electromotive force is superimposed with the power supply voltage to further increase the base current and collector current, forming a strong positive feedback. Through the coupling effect of L1 and L2, an induced electromotive force is generated at L1. Therefore, the collector current of VT starts to increase.
When the power supply is connected, a base current is provided to vt through R1. Its working principle is described as follows.Ĭ1, R1, VT, L1 and L2 are self-excited oscillation circuits which form positive feedback by transformer coupling. The circuit is powered by a single AA or AAA battery. The circuit shown in the figure below is the circuit schematic diagram of the electronic igniter.

Pulse igniter is a device that uses high voltage discharge spark to ignite the combustible gas of stove. Compared with the early piezoelectric ignition device, pulse ignition has high stability and simple operation. At present, it has been widely used in medium and high-end gas appliances, which greatly facilitates the use of customers and improves the level of product automation. With the improvement of industrial technology, the production cost of pulser has been reduced. Most of the early pulsers used dry batteries as power supply, but in recent years, most products have been converted to AC power supply. The so-called pulse igniter, referred to as the pulse igniter, is an electronic product that uses the pulse principle to produce a continuous instantaneous electric spark, thus igniting the gas with flame.
