中文摘要

本文提出了一种灵活的功率变换器控制技术,使其能同时作为有源电力滤波器和本地电源接口。该技术能够在向电网注入有功功率的同时补偿电流扰动,从而将功率变换器转化为多功能设备,有效提升了在畸变电网环境下的电能质量与运行灵活性。

English Abstract

This paper presents a flexible control technique for power electronics converters, which can function as an active power filter, as a local power supply interface, or perform both functions simultaneously. Thus, it can compensate for current disturbances while simultaneously injecting active power into the electrical grid, transforming the power converter into a multifunctional device. The main ob...
