Abstract

The micro-modular multilevel converter (

$\mu $

MMC) concept proposes a benchtop-scale, low-voltage, open-source, and affordable hardware prototype of a modular multilevel converter (MMC) intended for research and teaching applications. The

$\mu $

MMC (

$\mu $

originates from its rating being approximately one millionth of usual transmission-scale MMCs) aims to provide a solution to break the barrier from theory to practice, thanks to its all-integrated eight full-bridge (FB) submodules (SM) in a

$10\times 10$

cm printed circuit board (PCB) with a local microcontroller able to communicate with an external master controller. The electronics is rated for a 30 V dc bus voltage as typically found in traditional lab power supplies, providing both convenience and safety. This structure allows a lot of flexibility in terms of testing converter topology and control architectures. This article details the setup process of the

$\mu $

MMC into a 3-phase inverter to demonstrate its versatility and potential as a teaching and research tool.

认识微型 MMC

微型模块化多电平转换器（$\mu $ MMC）概念提出了一种台式、低压、开源和经济实惠的模块化多电平转换器（MMC）硬件原型，用于研究和教学应用。$\mu $ MMC（"$\mu $"源于其额定值约为普通传输级 MMC 的百万分之一）旨在提供一种解决方案，打破从理论到实践的障碍，这要归功于它在一块 10 英寸 10 厘米的印刷电路板（PCB）上集成了八个全桥（FB）子模块（SM），并带有一个能够与外部主控制器通信的本地微控制器。电子器件的额定总线电压为 30 V，与传统实验室电源中的总线电压相同，既方便又安全。这种结构为测试转换器拓扑结构和控制架构提供了很大的灵活性。本文详细介绍了将 $\mu $ MMC 安装到三相逆变器中的过程，以展示其作为教学和研究工具的多功能性和潜力。
