Power converters
2. Power converters for electric vehicles
2.11. Power losses
Example of a 100 kW converter
- The inverter consists of six switches, ie three modules - half-bridges.
- Each module produces 700 W losses.
- A 100 kW inverter with 98% efficiency produces 2 kW of power output.
- Losses must be diverted from a very small area of the chip.
- Thermal resistance and heatsink temperature are key factors.
- Water cooling offers the optimal solution.
