Increasing Efficiency of Electric Vehicle Powertrain Using IGBT Inverters With the rising cost of semiconductors and limited space for power inverters in electric and hybrid vehicle applications, the demand for efficient power electronics is increasing. Greater efficiency has a direct impact on the required size of both the surface area of the semiconductors and the cooling system. Power electronics efficiency also has a great impact on other powertrain components like the battery capacity further increasing the need for higher efficiency. This presentation discusses the different solutions used today that allows improved IGBT switching losses and expresses the limitations of these solutions. The new Reflex Gate Driver Technology is presented with description on how it can significantly improve IGBT switching losses. Reflex gate driver technology allows up to twice as much output current from the same IGBT die surface area. Additional improvements are presented like the use of variable switching frequency and optimized control algorithms for better energy management. Christian Pronovost, TM4 Inc.
