Vicor Corporation announced that it has received Gasgoo’s 2025 Best Technology Application Award for its BCM6135 bidirectional DC-DC power converter. This honor highlights products that bring impactful, forward-thinking design to the automotive sector.
The BCM6135 is an 800V-to-48V converter capable of delivering up to 2.5kW in an extremely small 0.015-liter package weighing just 58 grams. It earned the award for addressing long-standing power-management challenges and delivering one of the highest-density, fastest DC-DC conversion solutions available for modern vehicles.
Unmatched Performance and Innovation
BCM6135 is the only DC-DC converter for HV-to-SELV that utilizes Vicor’s proprietary Sine Amplitude Conversion (SAC) technology. This patented zero voltage switching method delivers symmetrical switching speed, efficiency, and transient performance.
Key performance benefits praised by the industry include:
- Highest Power Density: The BCM6135 reduces power system volume and mass by 50–80% compared to current solutions.
- Top Efficiency: It achieves a 33% higher peak efficiency of 97.3%.
- Fastest Transient Response: The module achieves an astounding current slew rate of 8.0M A/s, faster than any load in a vehicle and the fastest in the industry.
- Bidirectional Power: It is the only DC-DC converter that can produce the same peak power for both bucking (800V–48V) and boosting (48V–800V).
“The BCM6135 is transforming eMobility and enabling breakthrough innovations in automotive electrification,” said Greg Green, Director of Vicor Automotive Marketing. “This module allows OEMs to not only reduce power system volume by nearly 50% but also remove the 48V battery altogether, increasing vehicle range and performance. Winning this award validates our team’s commitment to pushing the boundaries of power conversion technology.”
Enabling next-generation vehicle systems
The BCM6135’s performance has a critical impact on next-generation automotive applications, including active suspension power systems. Its high slew rate and symmetrical power handling enable optimal energy recuperation, allowing over 90% of the power taken from the battery for suspension actuation to be returned to the main battery.
Mr. Peter Li, Research & Development Director at Hongfa, noted the significance of the technology, stating, “When it comes to active suspension, our OEM customers require a DC-DC converter with a response rate measured in milliseconds, otherwise, additional battery support is needed. Vicor’s BCM6135 power modules enable the competitive performance we need. Vicor power modules not only deliver the performance we need but they also significantly shorten our development time and have made designing this type of system much easier for us”.
The unique combination of features in the BCM6135 is also allowing customers to:
- Eliminate Low Voltage Batteries: The module supports the deletion of a low voltage (12V or 48V) battery in the vehicle, reducing weight and package space by up to 70% for the power distribution system.
- Support New Applications: The power density and fast transients will be key enablers for emerging IR heating systems in electrified vehicles.
