本文提出了一种通过使用动态可重构超级电容器（SC）组抑制电压瞬变的技术。该技术需要至少两个SC组将电源从主电源传输到完全隔离的负载。在充电、放电或空闲的三种状态之一中，所述组作为能量存储元件独立地操作，并且通过无物理接触的电感耦合功率传输技术动态地实现组从一种状态到另一种状态的隔离转换。所提出的技术在任何给定时刻都没有市电电源和负载之间的直接连接，功率传输完全隔离，内置共模和差模瞬态保护。银行的规模相对于各种类型的SC和系统参数进行了分析。两个原型系统的仿真和实验结果之间的比较，受到IEC 61000 -4-5标准规定的组合瞬态浪涌，提出了讨论，以显示所提出的概念的有效性和其适用性的不间断电源系统和应急电源。
This paper presents a technique for the suppression of voltage transients through the use of dynamically reconfigurable supercapacitor (SC) banks. The technique requires a minimum of two SC banks to transfer power from a mains supply to load in complete isolation. The banks are operated independently as energy-storing elements in one of the three states of charging, discharging, or idling, and transition of banks from one state to another with isolation is realized dynamically by inductively coupled power-transfer technology with no physical contacts. The proposed technique has no direct connection between the mains supply and load at any given moment, and power transfer takes place in complete isolation with built-in protection for both common- and differential-mode transients. Sizing of the banks with respect to various types of SCs and system parameters is analyzed. Comparisons between simulations and experimental results of two prototype systems, subjected to combination transient surges specified by IEC61000-4-5 standard, are presented with a discussion to show the validity of the proposed concept and its suitability for uninterruptible power systems and emergency power supplies.
