Current density of wiring : Most electronic circuits are now made of copper-bonded insulating boards. The copper thickness of commonly used circuit boards is 35μm. The current density value of the wiring can be taken according to the empirical value of 1A/mm. The specific calculation can be referred to the textbook. In order to ensure…

With the improvement of power semiconductor device performance and the innovation of switching conversion technology, power electronics technology has been widely used in various power supply equipment. At present, switching power supply products are becoming more and more small, high-speed and high-density. This trend has led to increasingly serious electromagnetic compatibility issues. The high-frequency switching…
