Description

This design is a digitally-controlled, solar DC/DC converter with maximum power point tracking (MPPT), for use in central or string solar inverters. It is a companion to the TI Design TIDM-SOLAR-ONEPHINV, a grid-tied, single phase, DC/AC inverter. Together, the TIDM-SOLAR-DCDC and the TIDM-SOLAR-ONEPHINV comprise a complete solar inverter for central or string topologies. This solar DC/DC converter consists of a two-phase interleaved boost converter for MPPT and a resonant LLC converter with isolation. A C2000™ Piccolo™ TMS320F28035 microcontroller (MCU) is the digital controller for the complete DC/DC converter, executing high frequency control loops and maximum-power point tracking algorithms. This design achieves full-load efficiency of greater than 94 percent, which allows for more overall energy output from a solar installation and reduces detrimental heat generation in the converter.

Features
  • Implements a solar DC/DC converter with maximum power point tracking (MPPT). The DC/DC converter consists of a two-phase interleaved boost converter for maximum power point tracking and a resonant LLC converter with isolation.
  • C2000™ Piccolo™ TMS320F28035 microcontroller (MCU) serves as a high-performance controller for the complete DC/DC converter, executing high-frequency control loops to control the power stages and compute maximum power point algorithms.
  • Supports input panel voltages of 200V to 300V and an output of 400VDC, rated up to 500W.
  • Greater than 94 percent peak efficiency allows for more overall energy output from a solar installation and reduces detrimental heat generation in the converter.
  • Solar and digital power software libraries provide code-optimized building blocks to implement a variety of power topologies and algorithms such as MPPT and Software Phase Locked Loops (PLL), perfect for designing customized solar inverter solutions.
  • Fully-functional evaluation board includes software, hardware design files, quick-start graphical interface and step-by-step documentation.

NOTE: Software for this board is located inside the controlSUITE™ software package. Download controlSUITE. Once installed, navigate to "High-voltage Solar Maximum Power Point Tracking Development Kit" under the Development Tools -> Solar section.
