Abstract
The overall objective of the Phase I effort was to establish the feasibility of a Solid State Lightweight Transformer (SSLT) Concept to significantly increase power density for 13.8 kV - 2.7 MVA class transformers. This was accomplished by developing a concept for the Solid State Lightweight Transformer (SSLT) System which consists of the following subsystems: 1) Transformer, 2) Switching 3) Thermal Management, and 4) Filtering. The phase I concept has the potential to reduce the size of conventional high power, high voltage transformers by a factor ranging from 3 to 5. . The Phase II technical objectives are as follows: Create the design a high power, high voltage (2.8 MVA, 13.8 kV -450 V, 3 phase) solid state lightweight transformer (SSLT) utilizing Silicon Carbide (SiC) switches operating at frequency greater than 15 kHz. Generate validated engineering design data resulting from technology maturation of: 1. Electrical insulation for high power, high voltage transformers and high frequency SiC switches 2. Lightweight transformer cooling and compact solid state switching modules 3. Lightweight transformers fabrication. Validate ship level SSLT benefits via inclusion in trade offs by ship yards and Navy architects Create a test bed to validate key performance features and increase credibility. Develop a product introduction plan.
