中文摘要

模块化多电平变换器(MMC)是高功率应用的关键技术,子模块(SM)的可靠性直接影响系统性能。本文提出一种部分功率硬件在环(P-HIL)测试方法,旨在开发阶段对单个子模块进行动态与稳态验证,以降低兆瓦级系统整体测试的成本与复杂性,确保其在各种工况下的可靠性。

English Abstract

Modular multilevel converter (MMC) has been highlighted as a scalable power converter for high-power applications. As a unit power block, submodule (SM) is a key component to achieve the scalability and reliability of the MMC. Therefore, it is important to test an SM under various operating conditions during the development stage before the final full assembly. To reduce the development cost and t...

该研究提出的P-HIL测试方法对阳光电源的研发具有重要参考价值。在阳光电源的兆瓦级储能系统(如PowerTitan系列)及大型集中式逆变器开发中,由于系统功率等级高,全功率测试成本极高。引入部分功率硬件在环测试,可以在研发早期阶段高效验证功率模块(SM)的动态性能与可靠性,缩短产品上市周期。建议研发团队评估该方法在储能PCS功率单元测试中的应用,以提升高压大功率变换器在复杂电网环境下的鲁棒性。
