The circuit in this Design Idea detects short-circuit faults or excess-current conditions in line-operated equipment, such as a UPS (uninterruptible power supply), across an isolation boundary. If the ...
This technical note is about isolated voltage or current sensing with the use of Avago’s ACPL-K370 / K376 Optocouplers. This article gives an overview of the ACPL-K370 / K376 Optocouplers. This device ...
Members can download this article in PDF format. Reliability of the power-conversion system is a critical issue, especially at high power levels. Application areas that fall under this umbrella ...
Insulated-gate bipolar transistors (IGBTs) require full protection to avoid damage and failures resulting from conditions such as short circuits, overloads and overvoltages. The protection is key to ...
