摘    要:基于电容储能式电控点火系统研究了一种火花持续期、次级火花电流可控的交流点火系统。利用CADENCE PSPICE软件以及模拟负载试验,验证了不同斩波电流、驱动脉宽等可变参数对交流点火系统火花能量的影响。试验结果表明:火花能量的提高依赖于斩波电流值的增大和驱动脉宽的延长,并近似呈线性关系;交流点火系统火花持续时间可实现2.5 ms内可控调节,初级斩波电流可实现30 A内可控调节。交流点火系统可通过相应参数的调节实现火花能量可控,最大火花能量可达到260 mJ,满足气体燃料发动机的功能需求。

关 键 词:交流点火系统  驱动脉宽  火花能量  试验

Abstract:Based on the capacitor-storing spark ignition system, the AC ignition system which can control spark duration and secondary spark current efficiently was researched. How different primary peak currents and driving pulse widths affecting the spark energy of AC ignition system had been verified by CADENCE PSPICE software and simulated load test. The test results show that the increase of spark energy is relied on the increase of primary peak current and extend of driving pulse width, and the relationship is almost linear; the spark duration of AC ignition system is controllable within 2.5 ms, and that primary peak current is controllable within 30 A.The AC ignition system can flexibly control spark energy by regulating related parameters, and the maximum value of spark energy could reach 260 mJ, thus meets the requirements of gas-fuel engines.
Keywords:AC ignition system  driving pulse width  spark energy  test
