The discussion revolves around the search for IGBTs operating at frequencies of 45, 55, and 65 Hz, with users struggling to find available options online. A clarification is made that while 45 to 65 Hz is not significant, frequencies between 45K to 65K Hz are important. Participants suggest using modeling tools like Semisel to define necessary parameters for the application. The conversation emphasizes the need for specificity in frequency requirements when searching for components. Overall, the thread highlights challenges in sourcing specific IGBT frequencies and the importance of accurate modeling in electrical design.
