When we design a current sense transformer (CST), we start with the electrical conditions around it rather than choosing a part from a catalog. A current sense transformer uses the magnetic field created by AC current in its primary to produce a proportional secondary signal that a control or monitoring […]
Electrical noise is one of the most persistent challenges in modern electronics. Whether you’re designing a switch‑mode power supply, motor drive, automotive controller or communication device, unwanted high‑frequency interference can degrade performance, disrupt signals, and cause compliance failures. A properly engineered common mode choke is one of the most effective […]
