A New Approach to Circuit Breaker Design Using Silicon Carbide Switches - Nov 21
Mechanical circuit breakers can be low cost with minimal losses, but they operate slowly and wear out. Solid state versions overcome the problems and are becoming increasing viable as replacements at...

Selecting the best IGBT for an application can be confusing and time-consuming, so is it worth the time? In this article, we will attempt to simplify the selection process by providing an explanation for the trade-offs to be considered. To illustrate the benefits, the author will describe the performance improvement possible with a new generation of 600V IGBTs targeted for DC/AC inverter applications. By using optimised trench IGBTs, IR can improve efficiency or reduce system heatsink size or increase current density out of the same board ass embly.
