Design of reliable power converters requires thorough understanding of the characteristics of semiconductor devices over wide range of operating and environmental conditions. This paper presents experimental investigations on switching characteristics of high-power Insulated Gate Bipolar Transistor (IGBT). The focus of this paper is to study turn-on delay time, turn-off delay time, voltage (dv/dt)...
In traction application, inverters need to have high reliability on account of wide variation in operating conditions, extreme ambient conditions, thermal cycling and varying DC link voltage. Hence it is important to have a good knowledge of switching characteristics of the devices used. The focus of this paper is to investigate and compare switching characteristics and losses of IGBT modules for...
