IGBT modules enhance effectivity in various purposes by means of a flexible housing design and simplified paralleling, offering cost-effective options.
The shift in the direction of offloading complexity to suppliers and adopting smaller IGBT modules is clear in numerous purposes. In response to the worldwide push for downsizing and integration, Infineon Applied sciences AG has launched the 4.5 kV XHP™ 3 IGBT modules for medium voltage drives and transportation purposes working at 2000 to 3300 V AC in 2- and 3-level topologies. Purposes embrace giant conveyor belts, pumps, high-speed trains, locomotives, and business, development, and agricultural autos.
The brand new housing for high-power IGBT modules is designed to cowl the voltage vary of IGBT chips from 3.3 to six.5 kV. Its scalability simplifies system design and manufacturing. Moreover, its structure supplies reliability in purposes with demanding environmental circumstances.
The XHP household includes a 450 A twin IGBT module with TRENCHSTOP™ IGBT4 and an emitter-controlled diode and a 450 A double diode module with an emitter-controlled E4 Diode.
Each modules function an isolation of 10.4 kV. They assist to simplify paralleling and downsizing with out sacrificing effectivity. Beforehand, busbars have been required to parallelize switching modules, leading to design efforts and leakage inductance. The design of the XHP household simplifies paralleling by inserting the connections facet by facet. Consequently, solely a single busbar is required for paralleling.
The 4.5 kV XHP household additionally permits builders to cut back the variety of items. Standard IGBT options use a number of single switches and a double diode. The brand new units can scale back designs to 2 twin switches and a smaller double diode.
Combining the XHP 3 FF450R45T3E4_B5 twin change and the DD450S45T3E4_B5 double diode permits value financial savings and a smaller footprint. For instance, Infineon’s earlier IGBT options required 4 140 x 190 mm² or 140 x 130 mm² switches and one 140 x 130 mm² double diode. The brand new XHP household can scale back the elements to 2 140 x 100 mm² twin switches and a smaller 140 x 100 mm² double diode.
