SBE has been using capacitor and interconnect technology to facilitate power module system integration since 2007, allowing for greater power densityA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitors, lower cost, lower ESRLow Equivalent Series Resistance and lower ESLLow equivalent series inductance.. SBE's new vertical testtest is test kits allow customers to do rapid prototyping of the topology without major investments in time and engineering resources.
The testtest is test kits received a great deal of positive attention at the APEC show in March. Such vertically-stackedMultiple capacitor elements stacked in multi-unit arrangement to provide bulk capacitance and lower ESR.Multiple capacitor elements stackedMultiple capacitor elements stacked in multi-unit arrangement to provide bulk capacitance and lower ESR. in multi-unit arrangement to provide bulk capacitance and lower ESR. inverter design is indeed well adapted for the transportation, alternative energy and distribution markets, and is scalable to any required power level.

A minimum width cooling plate will reduce the ESLLow equivalent series inductance. 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 testtest is 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 testtest is test kits is usable for the final design qualification. In fact, customers have literally "designed in" the testtest is test kit (minus the adapter plate) directly into their first prototype systems.
To order a testtest is test kit, customers simply need to identify their IGBT of choice, the voltage and DC Link capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. desired. SBE will deliver the integrated capacitor/bus assembly along with an adaptor for the particular IGBT.
