Online IGBT product selector and performance evaluation tool simplifies device optimization

March 07, 2013 // By Paul Buckley
International Rectifier has enchanced the company's IGBT selection tool that enables design optimization in a wide range of applications including motor drives, uninterruptable power supplies (UPS), solar inverters, and welding.

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

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 an indication of the relative performance of different IGBTs. With this information the designer can select the most cost-effective IGBT for the application.
