DC-DC converters convert HV to 48V, HV to 12V, and 48V to 12V in the various configurations of electric vehicles. The key design requirements for DC-DC converters are low losses, high efficiency, low volume and light weight. There are many architectures requiring different kinds of semiconductor devices. ST supplies power devices, super-junction MOSFETs with fast switching diodes, IGBTs with co-packed diodes, SiC MOSFETs, and low-Voltage Trench-Gate MOSFETs as well STGAP1S gapDRIVEâ„¢ as gate drivers.
Bidirectional DC/DC Converter
Electric vehicles (EV) use two different power systems; a high-voltage battery (200 to 450 VDC) for traction and a low-voltage (12 V) one for supplying...
