SCAPE’s on-board charging revolution

SCAPE aims at significantly enhancing the power density of automotive on-board chargers. SCAPE’s innovative approach utilizes traction motor stator windings and the traction inverter to develop a non-isolated integrated charger. This innovation not only replaces the need for currently used dedicated equipment in automotive applications but also offers cost, space, and weight savings by making the traditional equipment obsolete.

However, this configuration can result in a significant ground leakage current, posing risks of electric shocks and potential failures in on-board electronics, which hinders the practical application of this solution. SCAPE has thoroughly investigated the ground leakage current issue and proposes innovative solutions and modulation techniques. These strategies effectively mitigate this challenge, ensuring containment of the phenomenon. Additionally, they achieve high efficiency by leveraging wide-bandgap devices.
