SMALL INNOVATIVE PROJECTS IN SOLAR 2022- CONCENTRATING SOLAR THERMAL POWER AND PHOTOVOLTAICS THE AIM OF THIS PROJECT IS TO DEVELOP AND VERIFY A NEW APPROACH TO DESIGNING MEDIUM-VOLTAGE (MV) PLANAR TRANSFORMERS FOR EMERGING, UTILITY-SCALE, MODULAR PV SYSTEMS. THIS APPROACH CONSIDERS THESE MV PLANAR TRANSFORMERS AS SYSTEMS RATHER THAN AS COMPONENTS. THIS MEANS THEY CAN COMPRISE MULTIPLE INDIVIDUAL MAGNETIC CORES AND PRINTED CIRCUIT BOARDS (PCBS) WHICH CAN BE DISTINCTLY ORGANIZED BOTH ELECTRICALLY AND PHYSICALLY TO ACHIEVE MAXIMUM PERFORMANCE. A KEY ADVANTAGE OF THIS APPROACH IS THAT LOW-COMPLEXITY WINDING STACK-UPS CAN BE LEVERAGED WHICH SIMPLIFY PRIMARY-TO-SECONDARY INSULATION REQUIREMENTS, MITIGATE THE NEED FOR INTERLEAVED WINDINGS, AND AID IN STREAMLINING MANUFACTURING ABILITY AND COST. SUCCESSFUL DEVELOPMENT OF THIS FRAMEWORK GREATLY ADVANCES THE ABILITY FOR EMERGING MODULAR UTILITY-SCALE PV ARCHITECTURES TO ACHIEVE SETO’S LCOE TARGET OF $0.02/KWH BY 2030.
