Introduction
DC/DC Converter
The different systems of electric vehicles are powered by different voltages - propulsion, HVAC, window lifts, interior and exterior lighting, infotainment and seat belt sensors are just part of a long list. The on-board DC / DC unit must convert and distribute correct voltage to each system in a real-time manner, so that all systems can be integrated into one master system. Compared with any other silicon-based solution, Silicon Carbide devices ensure that the process can be faster, more reliable and more efficient.
On-Board Charger
On-board battery chargers are the key to keeping electric vehicles powered - they take alternating current from owner's home and convert it to direct current to charge the battery. They also usually can collect kinetic energy from vehicle itself to provide additional charge when braking. But traditional silicon has limited these systems in terms of output, size and speed.
