摘　　要：特斯拉线圈是一种在教育、科研等领域广泛应用的高压演示仪。为使特斯拉线圈可以更加安全、高效的应用于现代科研和教育活动中,研究给出了一种基于现代电力电子技术对传统特斯拉线圈改良的方案。在遵循其基本科学原理的基础上,对传统特斯拉线圈的火花间隙、高压直流供电源进行了取代,对其控制回路进行了闭环设计,增加了逻辑处理、中断控制、功率逆变3大主要电路。经过对电路原理的仿真分析和实际测试,结果表明,本方案对传统特斯拉线圈噪音大、寿命短、效率低等缺点起到了显著的改善效果,在线圈的安全性、可靠性等方面皆有较大的提升,实现了预期改进目标。Tesla coil is a kind of high-voltage demonstration instrument widely used in education,scientific research and other fields.In order to improve its security and efficiency,an improved edition of the traditional Tesla coil is given based on modern power electronic technology.Apart from its basic scientific principles being reserved,the spark gap and high voltage DC power supply are replaced,its control loop is closely designed and three main circuits of logic processing,interrupt control,power inverter are added.Simulation and testing of the new edition proves that the proposed scheme can greatly lower the noise,lengthen the life and improves the efficiency compared with the traditional one.Added with the improvement in security and reliability,the expected results are achieved.
