6. Frequently Asked Questions
1：What is the difference between a power module and a power assembly?
A power module typically refers to a standard packaged device with a defined footprint and specifications, such as an IGBT module or diode module. A power assembly or power component assembly is a higher-level integration that may include multiple modules, bus bars, capacitors, cooling structures, gate drives, and sensors pre-assembled into a single sub-system. Assemblies reduce system-level engineering effort and manufacturing complexity by delivering a more complete power stage.
2：When should I consider custom power assemblies?
Custom power assemblies are worth considering when standard modules cannot meet your form factor or performance requirements, when you need to reduce assembly time and improve manufacturing yield, when you require optimized thermal and electrical performance, when your production volumes are high enough to justify the engineering investment, or when you need to integrate multiple functions including power, sensing, control, and cooling into a single subsystem.
3：How do integrated power assemblies improve reliability?
Integrated assemblies improve reliability through factory-controlled assembly processes with consistent quality, optimized power loop design minimizing stray inductance, pre-validated thermal design, reduced number of interconnections and potential failure points, and standardized testing of the complete assembly before delivery. This is particularly valuable for high-voltage, high-current applications where field failures are costly and difficult to diagnose.
