Junction Temperature Estimation

An intelligent gate drive can deliver significant benefits to the whole converter – not just the power devices – and reduce both capital and operating costs through improved rating and condition monitoring. Estimation of IGBT and diode junction temperature and accurate measurement of on-state voltage are two of the enabling technologies to achieve this so-called “silicon squeeze”.

Junction temperature estimation leads to a number of OEM and operator benefits as summarised in this chart.
