IR upgrades IGBT product selection tool

International Rectifier (IR) has revealed that it has improved its Insulated Gate Bipolar Transistor (IGBT) selection tool. It added that the tool allows design optimisation in applications such as motor drives, uninterruptable power supplies (UPS), solar inverters and welding.

IR's IGBT selection tool evaluates application conditions including bus voltage, load current, switching frequency, short-circuit requirements, package and thermal system. New features include customisable thermal constraint setting and Current vs. Frequency output chart that conveniently compares devices over a range of operating conditions.

Located at http://mypower.irf.com/IGBT, the IGBT selection tool returns a shortlist of products that meet or exceed the application parameters entered by the user. The products are ranked by performance, with losses and junction temperature for the specified operating condition to help facilitate the selection process.

IGBT selection requires evaluation of many parameters that cannot be simplified into a single metric, as switching losses can be traded for conduction losses. To address this problem, IR's product selection tool generates a Current vs. Frequency graph that provides a powerful indication of the relative performance of different IGBTs, added the company.
