Second Generation SMPS Evaluation Board for DSP

Intusoft's Solar2TiM Dual Buck-Boost, Switch Mode Power Supply (SMPS) evaluation board is used for evaluating DSP simulation and design. Solar2TiM is set up for a 12V dc output at a current rating of up to 6A, with input ranging from 20 - 60V. Running as a solar-panel battery charger from two 205W panels, Solar2's input can connect to a 48V battery, with its output at 10V. The configuration is connected to the low side of the solar panel where it supplies 5.2A. Using a 48V system allows compliance with the US national electric code standard for low voltage devices. This eliminates the requirement for fencing ground installations.

The board is used as part of the "DSP Designer" software and firmware option with Intusoft's ICAP/4 analog and mixed-signal simulation tool suite. DSP Designer is an advanced integrated development system that translates the world of simulation from analog to digital, for digital signal processing (DSP), and provides real-time hardware equivalents to SPICE simulation AC, DC and Transient analysis results. The new Solar2TiM board provides enhanced operation over its Solar1 predecessor, and works with direct plug in to Texas Instruments and Microchip DSP evaluation systems.

Both input and output voltages for Soar2TiM can go as high as 60V dc with an input current up to 2A, and output current up to 6A. EMI filtering complies with the CISPR16 EU specification for solar panel noise. Extra test circuitry is provided with Intusoft's DSP Designer software to test for solar insolence (sunlight), so that the charger can be programmed to automatically power down when it is dark. Intusoft provides a test circuit schematic, parts list and equipment requirements for a solar panel simulation.
