Our D³ product is being developed out of an in-house need to enhance the response and control capability of the eddy-current dynamometers used in our own engine test cells. When used in conjunction with our own test cell control system, the D³ module has been used to greatly enhance the transient control capability of a standard dry-gap eddy-current dynamometer to the point that we were able to run engines through the highly dynamic LSI transient cycle and comfortably meet all cycle statistical requirements using only an eddy current dynamometer.  Sold as either an intelligent dynamometer coil driver or as a standalone dynamometer controller, the D³  will be available for sale externally in Q2 2007.
