摘要：研發了3.3kV 高速IGBT 模塊。優化壽命控制極大地降低了關斷損耗和恢復損耗。該高速特性適用于雙向和中頻應用，
例如諧振DC/DC 轉換器，展示了諧振DC/DC 轉換器模擬電路中IGBT 的開關行為和二極管的反向恢復行為。顯然，這種新設
計的模塊具有比傳統高速模塊更低的損耗，因此，更適合于雙向和中頻應用。該設計概念也可用于6.5kV IGBT 模塊設計。另外，對諧振DC/DC 轉換器模擬電路，將新設計模塊中二極管的損耗與3kV-SiC-JBS 損耗做了比較。 敘詞：高速IGBT，模塊，雙向，中頻 DC/DC轉換器，損耗 Abstract：3.3kV high-speed IGBT module is developed. Optimized duration control has significantly reduced the shuf-off loss and rerunloss. The high-speed feature is applicable to two-way and intermediate applications, such as harmonic oscillatio DC/DC convertor. Theswitching perforamance of IGBT and backward recovery performance of diode in harmonic oscillatio DC/DC convertor simulation circuitis demonstrated. It is obvious that the newly-designed module enjoys less power loss compared with the traditional high-speed module,which means it is more applicable for two-way and intemediate frequency application. The design concept can also be applied to thedesign of 6.5kV IGBT module. On the other hand, as for harmonic oscillatio convertor simulation circuit, the diode loss of newly-designedmodule and the 3kV-SiC-JBS loss are compared.
