The electrical schematic ends of double pressure electronic ignitor, its operating principle is as follows: the power supply voltage while in the unfavorable half cycle, the current with the V 1, L one and L 2 to C 2 charging, with the similar time, with the L one to C one filling turtle, once the provide voltage reaches the maximum value of 220V * V 2=311V, one and C C 2 charging voltage is about 300V, as a result of one-way conduction properties of V 1, U C2 voltage worth remains unchanged, although the U C1 gradually discharge, till the voltage is zero; when the energy supply voltage while in the positive half cycle, and by way of L one to L two the quantity of turns ratio is ten:

one, after L one right after boosting the output voltage is 3000V, the bulb lit at both ends of double voltage commencing circuit electronic ignitor is simple, simply because the thyristor latest with temperature is greater, the open voltage more than a broad range of drift reliability big difference. It's the early use of high-pressure sodium lamp electronic ignitor in recent times, two-way thyristor tube ignitor commonly utilised electrical schematic diagram, its working principle is as follows: once the provide voltage is half of your week, V2 ignitor conduction, C1 by way of L2 and discharges C2, L2 create induced electromotive force, the L1 coupling generates a pulse higher voltage, lighting fire started off; in electrical power from the adverse half cycle, lighting can even now fire begun three terminal electronic ignitor circuit.

Due to the limitations of some events, typically amongst outdoor lighting fixtures and high pressure sodium ballast, ignitor distance is very far, resulting in electronic output ignitor pulse voltage reduction all through transport towards the lighting, lighting at each ends of the voltage also very low and could not begin. It truly is suggested to utilize 3 end style electronic flip flops and 3 terminal sort ballast to start out the circuit, which can boost the electrical circuit as well as commencing characteristic. This circuit attributes: it uses the ballast inductance coil being a pulse transformer, to ensure that the amount of inductance enhanced, the discharge duration is prolonged, is conducive to lighting get started.
