Thermal Management – Engineering Deep Dive

In automotive power electronics, thermal management is a key factor for performance, reliability and lifetime. The focus is on robust, series‑capable solutions.

1. System Understanding

• Thermal behaviour as a system property
• Transient effects often dominate lifetime
• Hot spots ≠ system‑level risk

2. Simulation and Measurement

• CFD as guidance, not absolute truth
• Correlation with measurement
• Thermal impedance analysis

3. Materials and Interfaces

• TIM selection under series production conditions
• Ageing and tolerance effects
• Soldering, bonding and interconnection concepts

4. Validation and Reliability

• Temperature and power cycling
• Load collectives instead of single worst‑case points
• Link to FMEA and 8D processes

Objective: Robust, predictable thermal behaviour over lifetime.
