Integrated Modules Test Kits
SBE has been using capacitor and interconnect technology to facilitate power module system integration since 2007, allowing for greater power density, lower cost, lower ESR and lower ESL.
A line of vertical and horizontal test kits have been developed to allow customers to do rapid prototyping of the topology without major investments in time and engineering resources.
Vertical Test Kits
The vertically-stacked inverter design is well adapted for the transportation, alternative energy and distribution markets, and is scalable to any required power level.
In a vertically-stacked inverter design, the width of the required cooling plate for both the capacitor and the IGBT modules is directly proportional to the length of the bend in the configuration. A minimum width cooling plate will reduce the ESL at the IGBT. The ability of the SBE Power Ring film capacitor to provide very low heat dissipation for high ripple currents will facilitate this option.
The materials used in the test kits are identical to those in final product designs and can be subjected to the same stress levels as final products. Therefore all the electrical testing and life acceleration performed on test kits is usable for the final design qualification. In fact, customers have literally “designed in” the test kit (minus the adapter plate) directly into their first prototype systems.
Horizontal Test Kits
A different geometry could also take advantage of the electrical featuresof the Power Ring. The crown terminals’ connections provide extremely low ESL and improve significantly the inverter’s performance.
The horizontal test kit was designed to help customers integrate this geometry and terminal structure by connecting a universal bus on top of the component. The adaptor will then be customized depending on the dimensions of the IGBTs used.This type of test kit is especially used at the prototyping phase of any project. It provides a quick complete demonstrator that the customer is able to connect easily to evaluate the performance. Depending on the geometry and space available the horizontal test kit is also used in some cases in final designs.
To order a test kit, customers simply need to identify their IGBT of choice, the voltage and DC Link capacitance desired. SBE will deliver the integrated capacitor/bus assembly along with an adaptor for the particular IGBT.
