Paralleling of IGBTs and Diodes of One Power Module – Pushes Power Capability
نویسنده
چکیده
The increasing request for motor drives with higher power levels is also driving the demand for power modules providing higher currents. The conventional approach to fulfill this requirement is to look for dedicated high current power modules. This article describes the alternative approach of paralleling IGBTs and diodes within one power module to extend its power capability, for example using a 35A sixpack module as a 100A half-bridge. The conclusion is that this approach provides an advantage due to the improved thermal behaviour of several small chips rather than fewer big ones.

Five-Level Common-Emitter Inverter Using Reverse-Blocking IGBTs
In a high switching frequency operation of current-source inverter (CSI), a conventional way to obtain unidirectional power switches is by connecting discrete diodes in series with the high speed power switches, i.e. power MOSFETs or IGBTs. However, these discrete diodes will cause extra losses to the power converter. This paper presents experimental test results of high switching frequency fiv...

متن کاملOn the Loading of Power Modules in a Three Phase Voltage Source Converter
The loading of free wheel diodes (FWD) and IGBTs in the power modules of a Voltage Source Converter (VSC) are investigated. In converter duty, the FWD is utilized more then the IGBT. Presently, most FWD’s in power modules are optimized for inverter duty. This practice tends to undersize the FWD from a converter viewpoint. This design philosophy is examined in the paper. For this purpose, the or...
متن کاملCurrent Sharing and Redistribution in High Power IGBT Modules
The Insulated Gate Bipolar Transistor (IGBT) is now the favoured power semiconductor device for most medium power applications. One major difficulty with current IGBT manufacturing technologies is the inability to produce chips rated at more than 100 amps both reliably and cost-effectively. To achieve higher current ratings, a number of chips are connected in parallel to form a module; up to 32...
