In this work a comparison between 3-pin and 4-pin superjunction (SJ) MOSFET is performed. Firstly, the advantages of the 4-pin packaging solution are pointed out by means of analytical expressions and simulations. Then, a standard 3-pin MOSFET has been experimentally compared with the Kelvin package configuration counterpart both integrated in an on board battery charger. The experimental results allowed quantifying the performance improvement of the four terminal package in terms of reduced switching energy losses and working temperature. These features enable the device to operate at higher switching frequency.

Abstract
In this work a comparison between 3-pin and 4-pin superjunction (SJ) MOSFET is performed. Firstly, the advantages of the 4-pin packaging solution are pointed out by means of analytical expressions and simulations. Then, a standard 3-pin MOSFET has been experimentally compared with the Kelvin package configuration counterpart both integrated in an on board battery charger. The experimental results allowed quantifying the performance improvement of the four terminal package in terms of reduced switching energy losses and working temperature. These features enable the device to operate at higher switching frequency.File in questo prodotto:
