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.
Circuit diagram and working principle of electronic igniter Ignition head, ignition time and ignition power can be manufactured according to customer requirements. The connection of ignition rod, high-voltage rubber wire and igniter is convenient, safe and reliable.ĥ. With powerful power, it can directly ignite liquid fuel such as atomized heavy oil.Ĥ. Pulse discharge, the total discharge time is 6-15s.ģ. Stable ignition frequency, long arc and reliable performance.Ģ. 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. You can also contact our buyer service and get some buying guides.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. We hope to keep every buyer up to date with this fastest moving electronic industry and the latest products trends.
