C2000 Solar Inverter Development Kits ™ Jump start your solar design with high-voltage, string-ready, isolated inverter kit or low-voltage emulation kit Two new Piccolo-based solar developer kits from Texas Instruments bring advanced peripherals, application targeted development hardware, a comprehensive library of algorithms, and an industry leading development environment to the renewable energy market. These two kits enable designers to jump-start designs while evaluating different algorithms and topologies. Both development kits are built on the Texas Instruments C2000™ F28035 Piccolo MCU device. Running at speeds up to 60Mhz, the F28035 features up to 128KB of flash memory, a 12-bit 4.6MSPS multichannel ADC, ePWM outputs, and the control law accelerator (CLA). The CLA is an integrated floating-point coprocessor designed to run control algorithms without any processor interaction. The high voltage solar developers kit features the Concerto™ MCU to the inverter portion of the design offering the flexibility of having control code and communications code handled by a single processor. As part of the C2000 family of MCU devices, these boards are fully supported in the controlSUITE™ IDE. Within controlSUITE, designers can quickly find all of the necessary tools for the Solar Developer boards including both general purpose algorithm libraries as well as renewable energy specific functions. The high voltage isolated kit features a 300VDC compatible input stage supporting up to 500W. This dual controller design features a two switch interleaved boost stage for MPPT and an isolated LLC resonant DC/DC converter. A full bridge inverter stage with PLL AC line synchronization completes the secondary side of the board and features enhanced communications by utilizing the Concerto MCU to drive the control stage while also providing ethernet support to the board. The low voltage kit is designed for safe benchtop level experimentation. Supporting a 12VDC/50W input stage, this board also features built in PV emulation, a photo-diode for light sensing, a single switch DC/DC boost for MPPT, a DC/DC SEPIC stage for battery charging, and a full bridge AC/DC inverter stage capable of driving 24VAC.
