Abstract |
This paper compares and analyzes the voltage drop characteristics that occur in the event of a short circuit depending on the type of GaN HEMT power semiconductor with a phase leg voltage detection method. E-mode GaN HEMT and Cascode GaN HEMT are used as comparative samples, and characteristics are compared through LTspice simulation and experimentation. The analysis confirms that E-mode GaN HEMT results in a larger phase leg voltage drop, and demonstrates that the type of GaN HEMT power semiconductor should be considered when designing a short-circuit detection system with a phase leg voltage detection method. |
