A well-known British automotive manufacturer of luxury and racing cars set out to build an 800V to 400V bi-directional DC-DC converter for its next-generation hybrid supercars. The goal was to create a compact, reliable, and highly efficient power module that could operate at 13kW, while also meeting strict functional safety (ASIL B) and cybersecurity (ISO 21434) requirements.

To overcome this, the client partnered with eInfochips, leveraging its High-Power Center of Excellence (CoE) in the UK and deep expertise in power electronics. The project required end-to-end ownership, which included architecture design, hardware and firmware development, software integration, compliance, and validation, all within a tight schedule.

The converter was built around the Infineon AURIX™ microcontroller platform, providing a robust technology foundation. eInfochips identified functional safety gaps early in the development cycle, integrated safety libraries, and aligned hardware-software interactions to meet ASIL B and ISO 21434 cybersecurity standards. Through a rigorous design process, the team achieved a first-time-right design, avoiding costly board rework and delivering the complete software stack without the need for expensive AUTOSAR licensing.

Testing efforts were significantly reduced by leveraging eInfochips’s automated test scripts and reusable components. The design also underwent comprehensive EMC, environmental, and thermal validation to ensure compliance with global standards. The workflow utilized a suite of tools including Altium Designer, CAN tools, LDRA, and Candela Studio for end-to-end hardware and software development as well as verification.
