High Efficiency, Low Current, Switching Power Supply

The Phase I program will demonstrate, at hardware level, a prototype digital dc-dc converter that is subcompact and very high efficiency converter technology. It introduces advantages of very low weight/volume/component count, very low output ripple voltage, voltage isolation, negligible RFI/EMI and non-flammability. In Phase I a very high efficiency digital ceramic (programmable output) low power converter prototype suitable for military equipment insertion will be demonstrated that can be implemented well within the desired volumetric constraint with a minimum of external passive components. The digital subcompact hardware dc-dc converter prototype will feature a digitally selectable voltage output (e.g. 2V - 6V); software battery monitoring and extremely low output ripple voltage characteristics. In Phase I Extension the new concept of digital dc-dc transformer/converter will be demonstrated that is capable of near 100% converter efficiency operation.
