Abstract :
Power ratings of rectifying equipment can greatly exceed the capability of single rectifying devices. Parallel combinations of devices or equipments are a common means to increase current rating. One must ensure that current is shared fairly evenly between semiconductors under normal and overload conditions. This paper presents an analysis of current distribution among parallel semiconductors based on real case measurements in high power rectifiers with simultaneous current acquisition in all legs and devices.
