Power Electronics Case

State of the art aluminium cases are a proven solution but can be substituted with lighter and cost attractive enclosures, which contribute to reducing the overall GWP of the component. Röchling’s material and process experience combines all different requirements with full plastic or hybrid (metal-plastic) materials and gives the possibility to develop and produce highly innovative cases for power electronic devices for the Automotive Industry.

To ensure long-life functionality of the power electronics of HV systems, power electronics cases serve several purposes:

• Protection
  The case shields electronic components from external environmental factors.
• Thermal Management
  Provide efficient cooling to protect the components from overheating and to ensure their functionality.
• Electromagnetic Interference (EMI) Shielding
  EMI shielding in both directions to ensure the correct function of the power electronics, especially when it comes to switching operations like inverting or converting.
• Safety
  The case prevents direct contact with potentially hazardous components like high-voltage circuits.
• Mounting and Integration
  The case provides a platform for mounting electronic components like PCB’s and helps the integration into larger systems with mounting brackets or similar.
