Make or buy: the IGBT assembly conundrum
How do cost, reliability and power density influence system makers’ decision whether or not to adopt IGBT power stacks, Andy Extance and Power Dev’ ask ABB, Danfoss, Infineon and Semikron.
‘Focus on our strengths’ is a motto of our times. It’s likely to be heard in the fi nancial results of a giant multinational, or seen in the business plan of the newest startup. It leads in different directions depending on just what those strengths are. In power electronics, if they include engineering know-how in integrating IGBT modules, for example, your strengths might let you build an inverter from components alone. But if that’s not your strength, you might need a ready-made IGBT power stack.
