Thermal Interface - A Key Factor in Improving Lifetime in Power Electronics

Increased demand in lifetime is an ongoing trend especially in applications like e-mobility or renewable energies. Likewise, the demand in power density is increasing as well, leading to contradicting effects. As higher power densities lead to increased temperature levels, higher temperatures result in higher stress levels thus threatening to reduce the lifetime. Though new developments in power electronic components target to increase the lifetime, thermal management becomes more important to fully exploit the benefits fr0m these modern devices. The present paper focuses on the influence of thermal interface materials as a key parameter in thermal management. Measurements and test results are presented showing the influence to both, thermal and lifetime situation.
