Aerospace & Defense Power Systems
As platforms become more electrified, connected, and software-defined, the need for reliable power conversion continues to grow. This shift is accelerating demand for advanced power semiconductor technologies—including high-voltage BCD and GaN—that can support higher efficiency, improved power density, reduced thermal load, and more compact system designs. Those improvements can translate into longer mission life, reduced system weight, improved reliability, and better performance in even the harshest environments.
At the same time, national security concerns have increased the importance of secure, domestic semiconductor manufacturing. Aerospace and defense leaders need partners who understand the technical requirements of mission-critical applications and can support the need for resilient, U.S.-based supply chains. Polar is investing in the technology, infrastructure, quality systems, and compliance programs needed to support this next phase of semiconductor innovation.
