论文摘要
较低的传导功率损耗和有利于平行连接的正温系数，使碳化硅（SIC）金属氧化物半导体野外晶体管（MOSFET）成为现有硅绝缘门双极透射器（IGBT）技术的极好替代。这些特征与高开关频率操作相结合，可以设计高准确的DC-DC转换器，并具有最小化的过滤要求。本文调查了具有高临界电流（0.9ppm）的转换器的设计，该转换器可通过使用SIC MOSFET和基于可扩展的模块的转换器设计，旨在实现准确性而无需使用主动过滤器。
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.
