Overcurrent Detection Using an Integrated Rogowski Coil for an Electric Vehicles Inverter

Higher reliability and downsizing of the inverter circuit are the essential demands in electric vehicles. This paper proposes an overcurrent detection method in the inverter using an integrated Rogowski coil. Notably, the current detection which flows in power devices is vital for overcurrent protection when the switching fault occurs. The integrated Rogowski coil has been proposed as the switching waveform measurement. In this paper, the Rogowski coil is applied for the overcurrent detection for an electric vehicles inverter. This paper focuses on the overcurrent when the short circuit occurs on the switching leg, and the appropriate detection method using the Rogowski coil is determined and validated.
