摘要:

较低的传导功率损耗和有利于并联连接的正温度系数使碳化硅(SiC)金属氧化物半导体场效应晶体管(MOSFET)成为现有硅绝缘栅双极晶体管(IGBT)技术的优秀替代品。这些特性与高开关频率操作相结合,使高精度DC-DC转换器的设计具有最小的滤波要求。本文研究了一个转换器的设计与高精度电流(0.9ppm)提供0.05H的电磁负载,旨在实现不使用有源滤波器的准确性,通过使用SiC MOSFET和可扩展的模块为基础的转换器设计。

英文摘要:

The lower conduction power losses and the positive temperature coefficient that favours parallel connections, make Silicon Carbide (SiC) metal oxide semiconductor field-effect transistors (MOSFETs) to be an excellent replacement of existing Silicon insulated gate bipolar transistors (IGBTs) technology. These characteristics combined with high switching frequency operation, enables the design of high-accuracy DC-DC converters with minimised filtering requirements. This paper investigates the design for a converter with high-accuracy current (0.9ppm) supplying a 0.05H electromagnetic load, aiming to achieve the accuracy without the use of active filters, by using SiC MOSFETs and a scalable module-based converter design.
