Infineon’s CoolSiC device range is currently in use with multiple manufacturers, which include Delta Electronics, which is a provider of power and energy management and aims to support steps toward green energy transition and carbon emissions neutrality. The CoolSic device range has the potential to enable electric vehicles to function as emergency backup power stores. With the latest developments in bidirectional inverters and the development of a hybrid three-in-one system that is able to integrate solar energy, energy storage and electric vehicle charging, Delta’s innovation has made it so that electric vehicles can now have the potential to become a source of emergency power backup.
“Infineon has been spearheading the development of power semiconductors and power efficiency for many years”, said Raymond Lee, director of Delta PV Inverter business unit. “With the company’s devices, we were able to integrate three applications into one system, which allows us to take a giant leap toward green energy.”
The bidirectional inverter has the potential to be used as a supply for charging electric vehicles and batteries, at the same time acting as a backup power supply during power outages. The components from Infineon consist of the 1200 V M1H CoolSiC EasyPACK 1B modules and 1200 V CoolSiC D²PAK 7-pin, a surface mountable device. The three applications are integrated into a somewhat compact form factor since the whole setup has been packaged into a size of 425*865*160 mm. The output power capacity is 10 kW, which allows a maximum current output of 34 amps and it can achieve a peak efficiency of around 97.5 per cent.
One of the critical components for developing the three-in-one system includes the the1200 V M1H CoolSiC EasyPACK 1B module (F4-23MR12W1M1_B11) with incorporated NTC temperature sensor and PressFIT contact technology. Multiple components from Infineon are employed in the system, which also includes devices using CoolMOS C7 and TRENCHSTOP 5 IGBT technology.
