Comparison of IGBT modules focus on high power systems

Abstract

Power demand of modern systems can be very high. A very reliable power electronic component largely present in today's high power system is the IGBT (Insulated Gate Bipolar Transistor). However, for very high power systems, a series or parallel connection is required either to obtain a higher voltage blocking capability or to be able to handle high output current demands. In addition, a series or parallel connection may also be used for a better design (to improve project cost, reduce power loss, etc.). This paper provides the reader background information on IGBTs, its functionality, and the two different types of packaging. Furthermore, this paper provides information on comparison of the losses of series connection of lower rated modules to a higher rated module, and a simulation of parallel connection of lower rated IGBT modules to a single higher rated module. Moreover, a simulation comparing different frequency operations is also provided along with IGBTs costs study for a better scope of overall design projects considerations.
