The Need for Multi-Energy Power Converters

As electrification and renewable energy grow, power converters bridging multiple sources and loads are essential for modern energy systems. Key challenges include:

  • High Power Density: Converters must deliver high performance within tight size constraints.
  • High Efficiency: Minimizing energy loss, cost, and heat generation is crucial.
  • Continuous Operation: System must remain reliable, even during faults.
  • Bidirectional Energy Flow: Efficient transfer of energy between sources at different voltage and power levels (e.g. batteries and V2G).
  • Galvanic Isolation: Ensure safety for systems and users.
