摘要: 介绍了紧凑型Tesla变压器的工作原理和功能特点，在此基础上对电压1.0 MV、重复频率100 Hz的Tesla变压器和阻抗40 W、宽度40 ns的脉冲形成线(PFL)进行了一体化结构设计。用Tesla变压器的两个同轴开环铁芯作为PFL的内外导体，将传统的形成线结合在Tesla变压器中，从而脉冲发生装置具备了体积小、效率高、性能稳定等特点。设计的紧凑型Tesla变压器在CHP01电子束加速器上实现了对600 pF的PFL单次充电电压达到1.3 MV、重复频率100 Hz、平均电压1.15 MV的技术指标，该变压器在其额定电压和频率下的连续运行时间达到5 s以上。Abstract: The theory and characteristic of a compact Tesla transformer are introduced, and an unitized configuration design is performed for 1.0 MV, 100 Hz Tesla transformer and 40 W, 40 ns pulse forming line (PFL). Two coaxial open cores in Tesla transformer serve as the inner and outer conductors of PFL, and a traditional PFL is combined with the Tesla transformer, then the pulse generator can be smaller, more efficient, and more stable. The designed compact Tesla transformer employed in electron beams accelerator CHP01 can charge PFL of 600 pF for 1.3 MV voltage at a single shot, and keep 1.15 MV at 100 Hz repeated rates. Furthermore, a continuance run in 5 seconds is achieved by Tesla transformer under voltage and frequency ratings.
