Development prospects of silicon carbide in the automotive field

Nowadays, there are more electric vehicles on the road than ever before. In the minds of engineers in the automotive and semiconductor industries, flashing faster, smaller, and lighter future cars are often flashed. Silicon carbide, as a typical representative of the third generation semiconductor, is carbonized. Silicon devices have the above three advantages and can provide high-voltage and high-temperature components for electric vehicles, helping designers create competitive and energy-saving products to meet market demand.

Four of the five major automotive applications are suitable for silicon carbide

One is the on-board DC-DC converter. Different systems of electric vehicles—power propulsion, HVAC, window lift, interior and exterior lighting, infotainment, and some sensors—are driven by different voltages. The vehicle-mounted DC-DC converter must convert and distribute the correct energy to each system in real-time so that all systems can work as a whole. Silicon carbide devices ensure that this process is faster, more reliable, and more efficient than any silicon-based solution.

The second is the non-vehicle DC fast charger. It converts the external input AC to the DC power mode required by electric vehicles and stores it in the battery. Drivers who are used to filling up with gas for 5 minutes are not willing to wait a few hours before getting their car back on the road. The excellent switching speed of silicon carbide is the core of a series of new fast chargers.

The third is the car battery charger. It converts the DC power from the battery subsystem to the AC power of the main drive motor. When the vehicle is plugged into an external power source of the power grid, the rectifier circuit of the device converts the AC power source into a DC power source to charge the battery. The system also collects the kinetic energy generated by vehicle momentum through regenerative braking and sends it to the battery. In each stage, silicon carbide can perform these functions faster. Compared with silicon, silicon carbide is 60% smaller, and the device has less heat and energy loss.

The fourth is the electric vehicle powertrain / central inverter. The realization of all-electric vehicle drivetrains depends on the designer. The goal is to use less power and design a smooth system at a lower price to allow all moving parts to run faster. Silicon carbide can handle the high current with the industry's lowest drain-source on-resistance, which increases the endurance distance of consumers on a single charge.
