针对PIP-II注入系统提高注入率和场强的需求，设计了一种20kA、±0.12%平坦度的双电容器脉冲电源，采用薄膜电容与电解电容组合及能量回收技术，满足25年寿命要求。
AI 中文摘要
费米实验室已通过质子改进计划II（PIP-II）启动了其面向未来中微子实验的下一步发展。注入系统现在要求将注入率从15 Hz提高到20 Hz，并且Booster环中原始轨道凸起（ORBUMP）偶极磁体的场强需增加约30%[1]。四个串联连接的偶极磁体在上述注入率下需要3 kV、20 kA、660 μs的脉冲，平坦度为±0.12%。这是通过一个由十个并联单元组成的双电容器脉冲电源（PPS）实现的，该电源必须持续运行25年。该电源利用高压薄膜电容器产生波形的上升和下降部分；然而，在平顶部分，它会切换到一组6 F电解电容器组以满足平坦度要求。该电源采用能量回收技术，以降低高压充电电源的规格和运行所需的功率。
英文摘要
Fermilab has embarked on its next evolution for future neutrino experiments through the Proton Improvement Plan II (PIP-II). The injection system now requires an increase from a 15 Hz to a 20 Hz injection rate with approximately a 30% increase in the field strength from the original Orbital Bump (ORBUMP) dipole magnets in the Booster ring [1]. The four series connected dipoles will require 3 kV, 20 kA, 660 $μ$s pulses at the aforementioned injection rate with a flatness of $\pm$0.12%. This is achieved through a dual-capacitor pulsed power supply (PPS) comprised of ten parallel cells and must last for 25 years. The supply utilizes high-voltage film caps for the rise and fall portion of the waveform; however, it switches over to a 6 F electrolytic capacitor bank for the flattop portion to meet flatness. The supply utilizes energy recovery to reduce high voltage charging supplies and required power to operate.
