Functionally Safe HV/LV Multi-Port Converter
Our patented technology enables the development of Fail-operational ASIL D Multi-port Converter
- HV/LV
- LV/LV
Not only is the solution an innovation, but the way we implement it:
- Multi-channel HV and LV architecture with galvanic isolated planar transformers
- Redundant multi-path power conversion on the LV side to ensure continuous operation during faults
- High-frequency operation using SiC or GaN semiconductors for compact design and low losses
- Automatic fault detection and path switching to maintain power delivery
SiC / GaN based technology
Summary of the Key Advantages
- Only one fully integrated converter
- Internal power path redundancies, ASIL-D achievable
- Fail-operational architecture designed to meet ASIL-D requirements
- No additional LV battery needed
- Channels Load balancing included
This image shows the most important benefits of this innovation and comparison to the current solution
Our innovation, combining WBG semiconductors with ultra-compact planar transformers enables what was previously considered impossible:
- A fully integrated converter in a single unit
- Redundant ASIL-D-capable converter in a single unit
Key System Benefits
- Significant reduction in total system cost
- Elimination of multiple components: two separate batteries, one additional transformer, one additional converter, connectors, cables, and related hardware
- Lower production time and cost
- Reduced stock and logistics effort (production and after-sales service)
- Higher simplicity, even in aftersales — in case of failure, only one device needs to be checked, replaced, or repaired
- Lower weight and reduced installation space inside the vehicle
In short: less is more — and the benefits are substantial.
