Infineon – Reference Design: 11 kW SiC DC-DC converter for fast DC EV charging
This reference design provides a blueprint for the fast realization of bidirectional DC-DC converters with 11 kW and up to 800 V. Thanks to its soft-switching topology and a wide output voltage range from 550 V up to 800 V it can be re-used to accelerate the prototyping of DC EV charging and energy storage systems.
Features
– 11 kW at full output voltage range (550 – 800 V)
– Bi-directional power flow capability
– High peak efficiency >= 97.2%
– High power density: > 4 kW/l
– 1200 V and 1700 V CoolSiC™ MOSFETs
Benefits
– DC-DC converter blueprint for re-use in DC EV charging wallboxes and energy storage systems
– Enables attractive business models (V2G and V2B) for end customers
– Minimum losses and cooling efforts
– Small size and weight for easy installation
– Low cost per kW on system level
Competitive advantage
– 11 kW at full output voltage range (550 – 800 V)
– Bi-directional power flow capability
– High peak efficiency >= 97.2%
– High power density: > 4 kW/l
Target applications
– Chargers from 30 kW to 150 kW
– Chargers from 50 kW to 350 kW
– Energy Storage Systems
– Fast EV charging
– Power Conversion Systems
