On-Board DC/DC Converter

Wolfspeed Silicon Carbide is ready for the challenges that today’s EVs present, especially when it comes to on-board DC/DC converters.

Past to Present: A Revolution in Automotive Electrical System Design

The electrical systems in vehicles of the past were simple — responsible for basic lighting, providing ignition, and perhaps powering a basic sound system. Modern vehicles, however, have far more complex electrical requirements, including advanced lighting systems, infotainment platforms, navigational and guidance controls, and much more. Electric vehicles (EVs), in particular, have taken power requirements to a new level, and the rise of autonomous vehicles are unlocking even further complications in power design.

What this means for automotive power is changes to the on-board DC/DC converter responsible for providing power to this complex and diverse set of systems.

What Is an On-Board DC/DC Converter?

The on-board DC/DC converter is responsible for taking the DC power from the battery and converting and regulating the voltage to meet the needs of this varying set of systems. It must do so in real time, as many systems have interdependencies that require them to work as a collective unit. Failure can be catastrophic.

Traditional Silicon: Is It Up to the Challenge?

For EVs specifically, the need to have reliable and consistent power is paramount. Traditional silicon is simply not up for the challenges of modern EVs. Wolfspeed Silicon Carbide (SiC) on the other hand, is specially built to meet this need. With greater reliability and improved efficiency over any silicon-based solution, Wolfspeed Silicon Carbide is ready for the challenges that today’s EVs present, especially when it comes to on-board DC/DC converters.

Improved Reliability, Cleaner Power from Wolfspeed Silicon Carbide

Wolfspeed Silicon Carbide is uniquely capable of incredible reliability and efficiency, even in the most demanding power applications. In electric vehicle DC/DC converter applications, this can mean keeping mission-critical systems supplied with the right voltages consistently and sustainably, as well as keeping overall vehicle weight down for improved performance and efficiency.
