Nexperia and IAV aim to extract more power from every cell with their ONE Inverter concept. This innovative approach to high-voltage architectures enables more efficient use of available battery capacity. Through the dynamic control and allocation of battery sections via a software-defined architecture, functions that currently rely on separate power electronics systems can be combined into a single system concept. IAV developed the underlying software-defined system architecture and battery control strategy for the concept, while Nexperia contributed the necessary wide-bandgap semiconductor technologies.

Optimized Battery Utilization

Both partners cite the ability to control the battery cells according to their actual condition as the main advantage of the new concept. Instead of the entire battery being limited by its weakest cell, each cell can contribute to the overall performance based on its own capacity. This helps improve battery utilization and increase the system’s robustness.

This approach is made possible by Nexperia’s wide-bandgap semiconductor technologies, in particular a bidirectional GaN device that enables efficient and fast switching at the battery cell level, making the approach technically and economically feasible. Alternative semiconductor solutions would significantly increase system complexity and costs. In addition, the semiconductor manufacturer supports the system design with additional components. (se)
