„Econo“ my improvement in inverter-converter-moduldesign

To realise an economy inverter construction, it is a good solution to use high reliable and flexible mounting technologies with a lot of automated steps like Printed Circuit Board (PCB) technology for all components. This is valid specially for all power elements e.g. rectifiers, inverters and brakes. Now this problem is solved with the completion of the „Economodule-Productfamily“ offered from Siemens HL and eupec. Some extra marginal conditions like the thermal management in- and outside of the module and on the PCB have to be observed. The results of these points, which have been simulated, calculated and tested, e.g. about current capability of thickwire bonds are of great interest, because of all intern module connections are made in this flexible technology. A complete product family with rectifier and inverter for PCB mounting technology called „Econo“ is available. The product scale has been presented. Thermal management of some special parts, which are described, is indicated. The thermal marginal conditions are known and their influences are observed in module design.
