Abstract :
The paper deals with the experimental evaluation of the electrical and thermal behaviors of punch-through IGBT in parallel connections. The influences of the electrical parameters on the current sharing are evaluated and discussed. The thermal behavior of several ICBT devices in parallel connections in different experimental conditions are evaluated and discussed. Furthermore some issues on the negative feedback contribution coming from the heat sink looking for the reduction of the current imbalance are analyzed in loaded conditions.
