固态变压器允许附加智能，以增强电源和负载之间的电能质量兼容性。期望展示通过使用这种装置所获得的益处。半导体器件和转换器拓扑的最新进展促进了新提出的智能通用变压器 (IUT)，它可以隔离来自电源或负载的干扰。本文介绍了基于 IUT 的多电平转换器的基本电路和工作原理及其在中压应用。通过完整 IUT 电路的计算机仿真演示了各种电能质量增强功能。
The solid-state transformer allows add-on intelligence to enhance power quality compatibility between source and load. It is desired to demonstrate the benefits gained by the use of such a device. Recent advancement in semiconductor devices and converter topologies facilitated a newly proposed intelligent universal transformer (IUT), which can isolate a disturbance from either source or load. This paper describes the basic circuit and the operating principle for the multilevel converter based IUT and its applications for medium voltages. Various power quality enhancement features are demonstrated with computer simulation for a complete IUT circuit.
