Off-Board Electric Vehicle Charger Plugged into EV
Automotive

Fast Charging

By replacing traditional Si components with Wolfspeed Silicon Carbide upgrades, DC fast charger designs can realize significant gains in system efficiency, power density, and reliability.

Silicon Carbide is powering the future for Electric Vehicle Fast Charging

Fast charging DC stations can charge Electric Vehicles in just 30 minutes by bypassing the onboard charger (OBC) for rapid, direct battery charging.


Power Up Faster with Off-Board DC Fast-Charging Technology

Consumer expectations have always been shaped by past experience — and the way we travel by car is no exception. For the entire history of automotive travel, fossil-fueled cars could be easily replenished by a quick stop at a gas station. Correspondingly, one of the biggest challenges of electric cars is how long it takes to charge them and the availability of rapid-charge systems.

The Future of Off-Board DC Fast Chargers is Powered by Silicon Carbide

When drivers of electric vehicles (EVs) need a charge while on the go, the best option is off-board DC fast chargers, which enable rapid charging of EV batteries. Unfortunately, traditional silicon’s (Si’s) switching performance is limited, which means that even the fastest of Si-based chargers is still going to be too slow for the average consumer’s expectation. Alternatively, Silicon Carbide (SiC) and its unique physical properties enable superior switching speed and higher power delivery— which means an efficient charge.

Replacing Si with Silicon Carbide Can Mean Big Benefits for Fast Charger Systems

By replacing traditional Si components with Silicon Carbide upgrades, DC fast charger designs can realize significant gains in system efficiency, power density, and reliability. These fast charger designs are typically constructed with stacked groups of power conversion blocks that are each 20 kW to 60 kW.

Furthermore, Silicon Carbide enables a much simpler design that offers many benefits, including fewer components, reduced system cost, higher efficiency, smaller size, and better bidirectional charging for Vehicle to Grid (V2G) capability.

Wolfspeed WolfPACK™ Silicon Carbide Power Modules

Wolfspeed Silicon Carbide power modules can enable a simpler fast charging circuit topology using fewer components at very high efficiency (97.0% peak), switching at more than twice the frequency (45-250kHz). The higher frequency allows smaller magnetics and capacitors which, in turn, accounts for the smaller, lighter, and less costly system.

Wolfspeed WolfPACK™ FM3 and GM3 power modules are ideal for mid-power applications, including EV fast charging. The modules come in MOSFET half-bridge and six-pack configurations with a variety of mΩ options. The devices feature a baseplateless design, compact footprint, and press-fit pins, providing efficient, powerful performance while keeping system layouts straightforward for design and assembly processes.

The product family includes high performance Aluminum Nitride (AlN) substrate modules, which can reduce thermal resistance by over 50% and provide 7x higher thermal conductivity compared to Alumina.
