Texas Instruments: Solar Micro Inverter Development Kit TMDSSOLARUINVKIT

Description

CAUTION: This equipment operates at high voltages and currents which can result in hazardous electrical shock. Please make sure you understand and follow all necessary safety precautions prior to purchasing and operating.

TMDSSOLARUINVKIT  is a DIMM100 controlCARD based motherboard evaluation module which uses Piccolo F28035.  This development kit implements a complete grid-tied solar micro inverter. The Solar Micro Inverter Development Kit introduces designers to a fully-suitable MCU for solar micro inverter applications, and guides users seamlessly through the design process and application challenges. Users can evaluate the design initially through a simple graphical interface without the need to dive into code development. When ready to explore in further depth, detailed theory-based documentation guides users step-by-step through the software and hardware implementation by incrementally building from open loop to closed loop operation of the solar micro inverter.

Features

Hardware Features

• A complete solar-micro-inverter development platform with Isolated DC-DC and DC-AC power stage.
• Supports panel voltages of 28 to 45V at input. Hence an active clamp fly-back DC/DC converter with secondary voltage multiplier is implemented on the board to enable greater efficiency. 100kHz switching is used.
• Universal power output at up to 280W for 220VAC and up to 140W for 110VAC, making it suitable for the diverse requirements of worldwide solar markets. Inverter switches at 50kHz.
• 93 percent peak efficiency and less than four percent total harmonic distortion (THD) provide more power output per solar panel, reducing detrimental heat dissipation and increasing system longevity.
• The C2000 Piccolo F28035 MCU serves as a high-performance controller for the complete micro inverter system, executing high-frequency control loops for both the DC/DC and DC/AC power stages.
• Single MCU system implementation offers design simplicity and reduced system cost.
• Hardware Files are in controlSUITE at development_kits\TMDSSOLARUINVKIT_v100

Software Features

• Complete software source code, hardware design files and detailed documentation allow designers to see and understand exactly how the design was implemented, creating the foundation to begin their own unique solar power implementations.
• Firmware for closed current loop for DC-DC and DC-AC with DC bus voltage regulation loop, along with MPPT from panel is provided.
• 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.
