This is a DC/DC converter that converts the high-voltage battery of an electric vehicle
into low voltage (12V) and supplies power to the 12V power line for auxiliary equipment.
Since its founding in 1949, Shindengen has been cultivating power supply technology.
With the evolution of car electronics, the required vehicle loads are increasing,
while power supplies are required to be even more compact and lightweight.
To meet these demands, we adopt technologies such as low-loss soft switching circuits
and high heat dissipation and thermal distribution techniques.
In addition, full digital control using DSP enables optimal power control and safe design,
as well as communication with upper-level ECUs.
Features
As EVs continue to evolve, power systems are required to offer flexible design adaptability, scalability for high power, high reliability, and compatibility with next-generation high-voltage standards.
Our DC/DC converters are equipped with four key features to meet these demands.
Enable Fast and Flexible Development with Standardized Platforms
Shindengen’s standardized platform DC/DC converters enable quick implementation through shared technology and shortened development time. Furthermore, by using a modular base and customizing as needed, flexible design tailored to specific applications is possible. With a lineup ranging from 1 kW to 3 kW, waterproof and vibration-resistant designs are also available, contributing to the rapid development and reliability of EVs and next-generation vehicles.
Parallel Connection for Flexible Power Expansion
Shindengen’s DC/DC converters support parallel operation, enabling flexible scalability to accommodate increasing auxiliary power demands and high-current requirements. Additional units can be seamlessly integrated when needed, allowing smooth and efficient system expansion. Coordinated control and add-on control ensure stable operation and reliable power delivery. Furthermore, these converters are designed to work in cooperative operation with products from other manufacturers, maximizing design flexibility and adaptability for diverse system architectures.
Redundancy Support to Minimize System Downtime Risk
Redundancy-compatible DC/DC converters improve system reliability. By supporting redundant configurations, the risk of system shutdown is minimized, ensuring continuous operation and safe design even in the event of a failure.
800V Compatibility for Next-Generation High-Voltage Vehicles
Our DC/DC converters support up to 800V, meeting the needs of next-generation EV platforms. This enables compatibility with high-voltage systems, ensuring scalability and reliability for future vehicle architectures.
