TI TMDSHV1PHINVKIT

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.
