Analysis and Design of a 50-kW Two Stage Converters for EV Fast Charger With High Efficiency and Wide Output Voltage of 150–1000 V

Generally, the DC-DC converters used in DC fast chargers must cover a wide output voltage with a fixed input voltage, and a single module needs to supply 30-50 kW of power. When designing an LLC resonant converter to cover a wide output voltage with a narrow frequency at high power, a small magnetiz...
