Transformers and Flat Wire Toroids for Texas Instruments Solar Inverter Designs
Würth Elektronik’s transformers and flat wire toroids are recommended for high-power solar string inverters
Würth Elektronik's, in partnership with Texas Instruments, developed a 10 kW, three-level, three-phase grid tie inverter reference design for solar string inverters TIDA-01606. This project involved creating two flat wire toroids, MID-FLT, with 15 A of rated current. Also in this design are three EPX7 gate drive transformers, MID-HB, and three SN6501 push-pull transformers used to generate isolated bias supplies. This reference design is recommended for customers interested in high-power solar string inverters.
