TIDM-SOLAR-DCDC

C2000™ MCU solar DC/DC converter with Maximum Power Point Tracking (MPPT) reference design

TIDM-SOLAR-DCDC

Design files

Overview

This design is a digitally-controlled, solar DC/DC converter with maximum power point tracking (MPPT), for use in central or string solar inverters. The design acts as a front-end MPPT DC/DC converter for the TIDM-SOLAR-ONEPHINV, a grid-tied, single phase, DC/AC inverter. Together, they form a C2000-based solar inverter reference design for central or string inverter applications. This solar MPPT DC/DC converter consists of two power stages, a two-phase interleaved boost converter for MPPT, followed by an isolated resonant LLC converter. A C2000 TMS320F280049C microcontroller (MCU) is used for full digital control of the DC/DC converter control loops while executing the MPPT algorithm.

Features

Implements a solar DC/DC converter with maximum power point tracking (MPPT). The DC/DC converter consists of a two-phase interleaved boost converter for maximum power point tracking followed by an isolated resonant LLC converter.
C2000 TMS320F280049C microcontroller (MCU) serves as a high-performance controller for the DC/DC converter, executing high-frequency control loops to control the power stages and compute the maximum power point algorithm.
Supports input panel voltages of 200 V to 300 V and an output of 400 VDC, rated up to 500 W.
Greater than 94 percent peak efficiency.
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 Loop (PLL) for designing customized solar inverters.
Includes software, hardware design files, quick-start graphical interface and step-by-step validation of the software.
