Improved high power switching and rectification circuits

28 February 2001 Power Electronics / Power Management

International Rectifier has announced a new family of improved INT-A-Pak power modules for high-voltage, high-current switching and rectification circuits. The devices suit a number of industrial applications, including motor controls, uninterruptible power supplies (UPS), forklift trucks, battery chargers and welders.

The improved INT-A-Pak module features lightweight construction, high mechanical strength, and increased safety. IR says that its assembly techniques improve performance, reliability, and high temperature reverse bias (HTRB) characteristics. In addition, the new module casing is made from recycled polymers and meets stringent environmental requirements. IR offers more than 100 versions of the new INT-A-Pak module, featuring breakdown voltages from 400 to 1600 V with current handling capability up to 230 A for rectification and 160 A for switching applications.
