Active suspension systems in electric vehicles
48V power systems reduce losses and downsize power designs. Vicor is making the transition from 12V to 48V easier, delivering a competitive advantage
Solving 400V/800V EV fast-charging compatibility
Compact and lightweight
Flexible placement of power modules
Scalable to meet changing requirements
High efficiency
Efficient, high-power onboard conversion using high performance power modules
37kW of power in a small space
Vicor high performance power modules require dramatically less space than traditional discrete power solutions. This allows for flexible placement of power conversion within the vehicle where the alternatives simply would not fit. High efficiency conversion reduces the impact to the cooling system, which can be smaller and lighter as well.
Scalable power architecture
By adopting the modular approach, easily scale power to meet requirements by simply adding another module or swapping for a different module. This allows for the same power architecture to be deployed across vehicle platforms.
Tailored solutions
Our team of engineers collaborates with customers to tailor our modules to support specific needs and to architect new, efficient, modular power delivery networks that take full advantage of our modules. Using just a few power modules, possible solutions support hundreds of unique power network designs to achieving the best mix of power, weight, and package space.
The Power Delivery Network
The NBM9280 provides 37.5kW of 400V and 800V fixed-ratio conversion in a 92 x 80mm CM-ChiP package, enabling a high-efficiency and high-density scalable onboard solution for compatibility between EV batteries and roadside DC fast-charging stations. With a fixed-voltage conversion ratio, this converter with a transformation ratio of two makes the battery voltage of an 800V vehicle appear to be half the voltage (400V). The same is true for a 400V vehicle: the bidirectional capability of the NBM9280 allows the same module to be used for either step-up or step-down conversion. The NBM9280 can also provide a 400V source for air conditioning and cabin electronics during 800V charging, minimizing battery balancing circuitry. It can also be used to power legacy 400V accessories in new 800V architectures.
