本文设计了一种额定电压为25KV、10A(峰值功率250kW，占空比10%，平均功率25kW，脉冲长度≈1-2ms)的“长脉冲”调制电源。该电源基于多相谐振电源的直接调制，由有源整流器供电。开发的目标是生产一种紧凑型电源，具有低存储能量和高电力质量的公用事业电源。本文简要概述了该技术，并对设计选择进行了讨论。文中包括了实验室样机的初步结果。
This paper considers the design of a “long-pulse” modulator supply rated at 25kV, 10A (250kW peak power, duty ratio 10%, 25kW average power, pulse length ≈ 1 – 2ms). The supply is based on direct modulation of a multi-phase resonant power supply, fed by an active rectifier. The objectives of the development are to produce a compact power supply, with low stored energy and with high power quality at the utility supply. The paper provides a brief overview of the technology, followed by a discussion of the design choices. Initial results from the laboratory prototype are included.
