Active gate drivers (AGDs) enhance the controllability and monitoring of switching devices, especially for fast switching silicon carbide (SiC) power metal–oxide–semiconductor field-effect transistors ( mosfet s). To support information flow between gate driver, converter, and grid control units, high-performance digital infrastructure is required. This article proposes a practical strategy of assessing the benefits of using wireless communication technologies (WCTs) in power electronics systems (PESs) employing AGDs. First, information transmission routes (ITRs) are identified and located within a PES. Second, an ITR taxonomy is proposed, classifying ITRs and describing both application scenarios and requirements for every class. After presenting general advantages of WCTs over wired alternatives, seven specific WCTs are individually characterized. Subsequently, the benefits of using WCTs are evaluated for each ITR class, resulting in a specific recommendation for or against the use of WCTs, and at least one appropriate WCT for each ITR. Experimental results demonstrate that the wireless control of AGDs for SiC power mosfet s is feasible using Bluetooth low energy. It is shown that an exemplary AGD can be effectively controlled with an information transmission delay of less than 45 ms, which is sufficient for the intended target applications.

碳化硅功率 MOSFET 有源栅极驱动器的无线控制

有源栅极驱动器 (AGD) 增强了开关器件的可控性和监控，特别是对于快速开关碳化硅 (SiC) 功率金属氧化物半导体场效应晶体管 ( 场效应管）。为了支持栅极驱动器、转换器和电网控制单元之间的信息流，需要高性能数字基础设施。本文提出了一种实用策略，用于评估在采用 AGD 的电力电子系统 (PES) 中使用无线通信技术 (WCT) 的优势。首先，在 PES 内识别并定位信息传输路由 (ITR)。其次，提出了ITR分类法，对ITR进行分类并描述每个类别的应用场景和要求。在介绍了 WCT 相对于有线替代方案的一般优势之后，我们对七个特定的 WCT 进行了单独的描述。随后，针对每个 ITR 类别评估使用 WCT 的好处，从而提出支持或反对使用 WCT 的具体建议，并为每个 ITR 至少提供一个合适的 WCT。实验结果表明，SiC 功率 AGD 的无线控制MOSFET 使用低功耗蓝牙是可行的。结果表明，可以以小于45ms的信息传输延迟来有效地控制示例性AGD，这对于预期的目标应用来说是足够的。
