Abstract
Due to increasing electrification power semiconductors become more and more key components for modern vehicles. The objective of this study is to investigate current solutions and to identify new trends for power semiconductors. The investigation is split into two parts and is based on a typical application of today’s and future cars. The inverter for motor control is analyzed in terms of power semiconductors. The analysis covers requirements of the electrical properties of the power devices. The second part examines existing power semiconductors like PowerMOSFET and IGBT in low and high voltage boardnet respectively. Finally the requirements are compared to the existing devices. Based on this comparison a gap analysis is done to extract future trends for the power devices.
KEYWORDS – power semiconductors, HEV/EV, reliability, efficiency, HV boardnet
