Abstract

This paper presents an integrated coil design method for inductive power-transfer (IPT) systems. Because a medium-voltage direct current (MVDC) distribution network transmits power at relatively high voltages (typically in the tens of kV), accurate fault diagnosis using high-performance sensors is crucial to improve the safety of MVDC distribution networks. With the increasing power consumption of high-performance sensors, conventional power supplies using optical converters with 5 W-class output characteristics face limitations in achieving the rated output power. Therefore, this paper proposes a safe and reliable power supply method using the principle of IPT to securely maintain the insulation distance between the distribution network and the current sensor-supply line. A 100 W prototype IPT system is investigated, and its feasibility is validated by comparing its performance with conventional optical converters.
中压直流传感器中基于电感式功率传输电源的增强型线圈设计
本文介绍了电感式功率传输 (IPT) 系统的集成线圈设计方法。由于中压直流(MVDC)配电网络以相对较高的电压(通常为几十千伏)传输电力,因此使用高性能传感器进行准确的故障诊断对于提高中压直流配电网络的安全性至关重要。随着高性能传感器功耗的增加,使用具有 5 W 级输出特性的光转换器的传统电源在实现额定输出功率方面面临着限制。因此,本文利用 IPT 原理提出了一种安全可靠的供电方法,以确保配电网络与电流传感器供电线路之间的绝缘距离。本文研究了一个 100 W 的原型 IPT 系统,并通过与传统光电转换器的性能比较验证了其可行性。
