Exploring the Hidden Complexity of Modern Power Electronics Design – A Siemens White Paper

The Siemens white paper delves into the complexities of modern power electronics design, emphasizing the critical role of the power delivery network (PDN) in ensuring product performance. Failure mechanisms for PDN designs, such as high voltage drop and improper stackup, are discussed, along with the importance of integrated simulation tools to prevent issues. The white paper highlights the intricate interactions between electrical, thermal, and reliability constraints, underscoring the need for a comprehensive design and verification flow. It also addresses key PDN failure mechanisms, including improper stackup, capacitor selection, thermal stress, and using components beyond specifications. The paper advocates for automated, simulation-driven workflows to tackle the challenges posed by modern power electronics systems.
