The TMDSSOLARUINVKIT is a digitally controlled solar micro inverter development kit. This development kit implements a complete grid tied solar micro inverter based on C2000 Piccolo TMS320F28035 microcontroller (MCU). The TMS320F28035 is a Piccolo microcontroller with 60MHz frequency, 20KB RAM and 128KB flash memory. 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.
- Implements control of an active clamp flyback DC/DC converter
- Supports panel voltages from 28V to 45V at input
- 93% peak efficiency and less than 4% total harmonic distortion provide more power output
- Executes high frequency control loops for the DC/DC and DC/AC power stages
- Single MCU system implementation offers design simplicity and reduced system cost
- Operates at 100KHz PWM frequency to reduce harmonic distortion
- Piccolo F28035 MCU enable efficient control of each power stage
- Solar and digital power software libraries provide code optimized building blocks
