Reference Designs

  • Primary-Side Regulated Flyback w/85-265VAC Input High Output Energy Storage Reference Design
    PMP8930.5: The PMP8930 reference design uses the UCC28710 primary-side regulated flyback controller to generate a 20V output from a univeral AC input. a bulk capacitor with slow-charge-fast-discharge circuit is placed at flyback output to provide long hold up time for the following step-down DC-DC stages. TPS54335 is used as the controller and power stage for the main 4V or 12V output. The valley switching of the UCC28710 allows this low-cost design to achieve a maximum load efficiency of 83%; no load losses are less than 70mW.
  • Primary-Side Regulated Flyback w/85-265VAC Input High Output Energy Storage Reference Design

  • TIDM-SOLARUINV Grid-tied Solar Micro Inverter with MPPT | TI.com
    TIDM-SOLARUINV: This design is a digitally-controlled, grid-tied, solar micro inverter with maximum power point tracking (MPPT). Solar micro inverters are an emerging segment of the solar power industry. Rather than linking every solar panel in an installation to a central inverter, solar micro inverter-based installations link smaller, or “micro,” inverters individually to each solar panel. This configuration lends itself to many benefits, including elimination of partial shading conditions, increased system efficiency, improved reliability and greater modularity. For this design, a C2000™ Piccolo™ TMS320F28035 microcontroller (MCU) is the digital controller for the complete inverter, including control of the power stages, MPPT, and grid-tie synchronization. The power conversion stages include 1) an active clamp fly-back DC/DC converter with secondary voltage multiplier and 2) a grid-tied, DC/AC inverter. The design achieves 93 percent peak efficiency and less than 4 percent total harmonic distortion, providing more power output per solar panel, reducing detrimental heat dissipation, and increasing system longevity.
