Using DC-DC converter power modules with industry-leading power density and innovative architectures equips power designers with solutions to reduce vehicle weight, power system space and overall cost. See how three new automotive grade products will accelerate the future of EV power system design.

The electrification of the automobile is presenting new challenges for power system designers in achieving the highest power density at the lowest weight possible, eliminating compromises in vehicle range and overall performance. Designers of power delivery networks (PDNs) are also tasked with designing safe, efficient and lighter weight system, without impacting cost – a very tall order.
Using DC-DC converter power modules with industry-leading power density and innovative architectures equips power designers with solutions to reduce vehicle weight, power system space and overall cost. A fully optimized PDN using 48V zonal architecture and high-density power modules will provide up $100 in cost savings and up to 25kg (55 lbs) in weight reduction.
Figure 1: Replacing conventional, discrete power conversion with power modules throughout the vehicle provides significant cost and weight savings in EVs.
Power modules can unlock significant new power system design opportunities enabling rapid innovation, when compared to custom, ground up, discrete power designs. Three new automotive grade Vicor DC-DC power modules can enable rapid power scaling and faster power system design across platforms and applications providing the vehicle team with solutions that are flexible, scalable and reusable. The BCM6135, DCM3735 and PRM3735, leverage the long Vicor heritage and leadership in power density and highly efficient power conversion. Just as important, their compact size and light weight make them an excellent choice for automobiles.
The three modules can be arranged in over 300 PDN configurations to support subsystems throughout the vehicle. The three parts can be used to convert 800V power supply to either 48V or 12V at power levels between 2 and 20kW, for virtually all high voltage power conversion needs. They are especially well suited to support the transition to 48V and 48V zonal architectures. Also, by leveraging their bidirectional capabilities, the modules are best able to support regenerative power loads as they are capable of changing current flow with the fastest current slew rates seen in the automotive industry. This product line has been developed and qualified for automotive use via the APQP process and will be rolling off new high-performance automobile assembly lines in the next 12 months.
Figure 2: Vicor BCM6135, DMC3735 and PRM3735 power modules have set a new standard for power density in the automotive industry. Collectively they solve complex conversion challenges with 800V, 400V, 48V and 12V systems for xEVs power systems.
Vicor power modules support modular scaling with parallel array capability and are so small that they can be used in a wide variety of applications. These parts are the building blocks for electrifying and innovating today’s EV.
The BCM6135 is a 2.5kW isolated BCM® Bus Converter which converts 800V to 48V in a package of 61 x 35 x 7.3mm. It the high-voltage BCMs. provides an industry-leading power density of 158kW/l. In addition to its power density, the BCM6135 has a current slew rate (di/dt) of 8MA/s. This performance is made possible by Vicor Sine Amplitude Converter™ topology and ZVS/ ZCS (zero voltage/zero current) switching control systems.
The DCM3735 2.0kW DCM™ DC-DC Converter converts an unregulated 48V input into a regulated 12V power supply. The DCM3735 has wide input range compatible with a variety automotive applications. The output can be trimmed within a range to 8 – 16V and it has a power density of 300kW/ l and supports downstream conversion and regulation from the high-voltage BCMs.
PRM3735 is a 2.5kW PRM™ Regulator for 48V power supply. The PRM3735 provides regulation at an efficiency of 99.2%. It has a small footprint and 260kW/l power density that helps free up packaging space downsizing the overall DC-DC power supply.
These new modules help OEMs achieve important EV power system design objectives:
The three new automotive modules serve as a Swiss army knife™ for power engineers. They can be used alone or in combination to streamline the design process and produce systems that are more efficient and lighter weight. So how are power modules being used today
Figure 3: Combining a BCM6135 with 48V delivers optimal performance and reduces size and weight of the power system. Given the high slew rate and high efficiency of the BCM6135, the system can achieve almost the same bi-directional power transmission for regenerative power as a direct cable without needing to rely on an auxiliary battery or high-voltage cables.
The electrification of automobiles is one of the most daunting design issues the automotive industry has ever faced. Adding battery cells and electronics balloon the vehicle weight and compromises range and performance. Designing with high-density power modules is the perfect solution for high-voltage conversion and to counter the impact of the heavy electronics.
Vicor, with its industry-leading power density, simplifies the job of the power engineer and helps stabilize the future xEV platforms using just three power modules: the BCM1635, DCM3735 and PRM3735. These compact products allow the PDN designer to downsize the hardware needed for DC-DC power conversion, leverage the smaller systems for integration into the battery or other power management boxes, and reduce the weight of the cooling system. Vicor modules also open the door not only to pioneering innovation, but also to definitive cost and weight savings. These three modules provide the basis for achieving up to $100 in cost reduction and reducing vehicle weight by up to 25kg.
