Designing high-power parallel arrays with PRMs
Outdoor charging station
Key challenges
- Develop a complete power supply that uses high-voltage electric car battery input (400VDC) which should then control and regulate the output for charging
Solution
- Using PRMs and VTMs allowed for the high efficiency and power density required
