摘要
本文重点研究了使用1.2 kv 400 a SiC-MOSFET/SBD h桥模块以及单位匝数变压器的双向隔离dc-dc变换器的精确转换效率测量。一个专门设计的效率测量测试台的特点是两个相同的750-V 100-kW 16-kHz双向隔离dc-dc转换器级联连接。虽然试验台配备了两个相同的单位匝比变压器，但两个变流器都能够在0.87至1.13的不同电压比下工作。实验结果表明，在额定功率为100kw，电压比为1.13时，直流输入到直流输出的整体转换效率高达98.9%，在另一电压比为0.87时，在100kw时，整体转换效率高达98.6%，其中不包括82 W的辅助功率损耗。
Experimental Characterization of a 750-V 100-kW 16-kHz Bidirectional Isolated DC-DC Converter With a Unity-Turns-Ratio Transformer at Different Voltage Ratios
This paper focuses on precise conversion-efficiency measurement of a bidirectional isolated dc-dc converter using the 1.2-kV 400-A SiC-MOSFET/SBD H-bridge modules, along with a unity-turns-ration transformer. A specially-designed test bench for efficiency measurement is characterized by the cascade connection of the two identical 750-V 100-kW 16-kHz bidirectional isolated dc-dc converters. Although the test bench is equipped with two identical unity-turns-ratio transformers, both converters are capable of operating at different voltage ratios ranging from 0.87 to 1.13. Experimental results verify that the whole conversion efficiency from the dc input to the dc output is as high as 98.9% at the rated power of 100 kW with a voltage ratio of 1.13, and 98.6% at 100 kW with another voltage ratio of 0.87, excluding an auxiliary power loss of 82 W.
