本文提出了一种利用SiC-mosfet/SBD h桥模块对大功率双向隔离双有源桥（DAB） dc- dc转换器进行损耗击穿的先进方法。该方法简单实用，可以从精确测量的总损耗中提取开关损耗。本文设计并构建了一个试验台，其特点是将两个相同的750-V 100-kW 16-kHz DAB变换器级联，并配备两个相同的单位匝比变压器。测试台架允许在降压和升压操作时的功率损耗击穿。当直流输入电压为750 V与直流输出电压为850 V在100kw和16khz时不同时，“混合”相移控制使总功率损失比“纯”相移控制低158 W。
This article presents an advanced method for power-loss breakdown of a high-power bidirectional isolated dual-active-bridge (DAB) dc-to-dc converter using SiC-mosfet/SBD H-bridge modules. This method is so simple and practical as to extract a switching loss from accurately measured overall losses. A test bench designed and built in this article is characterized by cascading the two identical 750-V 100-kW 16-kHz DAB converters equipped with the two identical unity-turns-ratio transformers. The test bench allows power-loss breakdown at buck and boost operation. When a dc-input voltage of 750 V is different from a dc-output voltage of 850 V at 100 kW and 16 kHz, “hybrid” phase-shift control makes the overall power loss lower by 158 W than “pure” phase-shift control.
