本文提出了一种用于脉冲负载应用的高压体电容器充电的DC/DC变换器拓扑结构。该拓扑结构是反激变换器的紧凑变体，具有完全软开关、变频控制和最佳磁设计。该转换器能够有效地将功率从30 V输入传输到从0 V充电到6 kV的电容器。该转换器的具体应用是用于超声波应用的脉冲火花器，但这可以应用于大量应用，例如除颤器，通信，脉冲武器系统和工业应用。经过实验测试，发现该转换器的峰值效率大于92%，整个充电周期的平均效率大于89%。样机功率密度大于1kw /L，有潜力达到2.5 kW/L。
This paper presents a DC/DC converter topology for charging high voltage bulk capacitors for pulsed load applications. The topology is a compact variant of the flyback converter with completely soft switching, variable frequency control, and optimal magnetics design. This converter is capable of efficiently transferring power from 30 V input to a capacitor charging from 0 V to 6 kV. The specific application for this converter is a pulsed sparker for a sonobouy application, but this can apply to a large number of applications, such as defibrillators, communications, pulsed weapons systems, and industrial applications. The proposed converter was experimentally tested, and found to have peak efficiency greater than 92%, with an average efficiency greater than 89% for the entire charging cycle. The power density of the prototype is greater than 1 kW/L, with the potential to achieve 2.5 kW/L.
