What is self-turn-on of switching elements?

The term self-turn-on is often used in the power electronics industry. Self-turn-on is a problem that occurs in bridge circuits, and is also called false firing.
This phenomenon can be difficult, especially for those new to power electronics, but it can be countered by understanding the principle of self-turn-on.

This technical document provides a detailed explanation of the mechanism of the self-turn-on phenomenon, including circuit diagrams. We also provide explanations from the perspective of circuit countermeasures and switching element characteristics.
Using Infineon's SiC MOSFET as an example, we also touch on how to use and benefit from products with strong self-turn-on characteristics.
For those new to power electronics, Infineon's SiC MOSFETs are easy to use and will be useful in future design and development.

Gaining a deep understanding of the causes and countermeasures for self-turn-on is the key to success in the field of power electronics.
Therefore, please take this opportunity to deepen your knowledge and apply it to your future projects.
