Engineering specialist IAV and semiconductor specialist Nexperia have jointly developed the ONE Inverter concept, a software-defined approach designed to optimize high-voltage battery architectures for electric mobility. Unveiled on June 11, 2026, this concept integrates Nexperia’s wide-bandgap semiconductor devices—including both gallium nitride (GaN) and silicon carbide (SiC)—with IAV’s system-level software and battery control strategies to make more efficient use of each individual cell.
The core innovation of the ONE Inverter is its ability to dynamically manage and allocate battery sections based on the real-time condition of each cell. Rather than limiting overall performance to the weakest cell, this architecture allows every cell to contribute according to its own health and capacity. This granular control can enhance energy utilization, boost system resilience and improve overall battery longevity.
Key to this approach is a bidirectional GaN device from Nexperia, which enables high-speed, high-efficiency switching directly at the cell level. This capability not only reduces power losses but also streamlines system complexity and lowers costs compared to traditional semiconductor solutions. Additional components from Nexperia’s broad semiconductor portfolio, including advanced bipolar devices, further support the integrated system design.
IAV’s contribution centers on a software-defined system architecture that governs how battery sections are controlled, monitored and reconfigured. By combining its expertise in battery engineering and vehicle architecture with Nexperia’s semiconductor packaging know-how, the two companies aim to establish a scalable framework for future software-defined electric vehicles.
Jörg Astalosch, CEO of IAV, noted that the collaboration demonstrates how system-level innovation can unlock new efficiencies, flexibility and robustness in electric mobility. Edoardo Merli, head of Nexperia’s Wide Bandgap, IGBT & Modules business group, added that aligning semiconductor capabilities with system requirements at an early development stage is critical to delivering high-performance, cost-effective solutions.
A laboratory demonstrator of the ONE Inverter concept was showcased at the Advanced Automotive Battery Conference (AABC) Europe 2026 and PCIM Europe 2026, where it attracted significant industry interest.
