Abstract

А high-voltage multicellular power supply with energy transfer through a current loop and current transformers is considered. The power source (static-electricity converter) consists of an inverter that generates a current with a preset magnitude in a current loop, which consists of a cable segment, and current transformers, the primary winding of which is represented by a current loop, as well as controlled rectifier cells. Such a decision makes it possible to provide a reliable isolation level between the input and output circuits of the source with a rather simple design of the device. Owing to the use of the same type of rectifier cells in the structure, one can provide a simple scaling of the source according to the output voltage level, as well as a simple setup and repair of the device. The principle of operation has been considered, and the choice of engineering solutions for the main components of the device has been justified. A system for stabilizing rectifier cell output voltage has been investigated as an automatic control system with pulse-phase control. The frequency characteristics of this system for two modes of energy transfer to the load are obtained, the modes are compared, and the most promising one is determined. A mockup of a 10-kV power supply has been manufactured and tested. The results of testing have confirmed the correctness of the calculations and the efficiency of the proposed approach.

通过电流互感器传输能量的电源
摘要А 本研究考虑了通过电流回路和电流互感器进行能量传递的高压多极电源。电源(静电转换器)由逆变器和电流互感器(电流互感器的初级绕组由电流环路表示)以及受控整流单元组成,逆变器在电流环路中产生预设幅值的电流,电流环路由电缆段和电流互感器组成,电流互感器的初级绕组由电流环路表示。这样的设计可以在信号源的输入和输出电路之间提供可靠的隔离水平,而设备的设计却相当简单。由于在结构上使用了相同类型的整流单元,因此可以根据输出电压水平对信号源进行简单的缩放,也可以对设备进行简单的设置和维修。对工作原理进行了考虑,并对设备主要组件的工程解决方案的选择进行了论证。对整流电池输出电压稳定系统进行了研究,该系统是一个具有脉冲相位控制功能的自动控制系统。获得了该系统向负载传输能量的两种模式的频率特性,并对这两种模式进行了比较,确定了最有前途的一种模式。一个 10 千伏的模拟电源已经制造完成并进行了测试。测试结果证实了计算的正确性和建议方法的效率。
