Development Kits

Jump start your solar design with development kits for micro, central and string inverters

C2000™ Solar Development Kits provide

instructive development platforms for

design of highly efficient and reliable solar

inverters, including central, string and

micro inverter topologies. These kits en-

able designers to jump-start solar inverter

designs using leading technologies found

in the solar industry today.

Solar development kits offered today

include:

•

Solar Micro Inverter Development Kit

•

Solar DC/DC MPPT Development Kit

•

Solar AC/DC Single Phase Inverter

Development Kit

•

Solar Explorer Development Kit with

F28M35H52C MCU

•

Solar Explorer Development Kit with

Piccolo TMS320F28035 MCU

The

Solar Micro Inverter Develop­

ment Kit is based on the Piccolo™

TMS320F28035 microcontroller and

serves as a complete grid-tied solar micro

inverter. The topology of the micro inverter

consists of an active clamp fly-back DC/DC

converter with secondary voltage multiplier,

maximum power point tracking (MPPT),

and a grid-tied DC/AC inverter. The single

Piccolo MCU functions as the controller for

the complete inverter, including control of

both power stages, and MPPT execution.

The

Solar DC/DC MPPT Develop­

ment Kit is based on the Piccolo

TMS320F28035 MCU and serves as a

DC/DC converter with maximum power

point tracking (MPPT) for central or string

inverters. Its companion kit, the

Solar

AC/DC Single Phase Inverter Develop­

ment Kit, is based on the F28M35H52C

MCU (alternatively supports the Piccolo

TMS320F28035 MCU as well), and serves

as a full-bridge, single-phase, grid-tied DC/

AC inverter for central or string inverters.

Together, the Solar DC/DC MPPT Develop-

ment Kit and the Solar AC/DC Single Phase

Inverter Development Kit operate as a

complete central or string solar inverter.

The Solar Explorer Development Kit

is designed as a low-voltage learning
