During the development of power electronics and industrial control systems, engineers often encounter two common problems:
High-frequency EMI emissions that fail EMC tests
Insulation breakdown during high-temperature and humidity aging tests
In many cases, the root cause is not the circu...
Excessive inrush current is a common challenge in switching power supplies. During startup, a typical 300W SMPS can experience surge currents of 50A–100A, which may damage rectifier bridges, weld relay contacts, or shorten system life.
