Synchronizing Three or More UCC28950 Phase-Shifted, Full-Bridge Controllers
Texas InstrumentsOne of the key features of the UCC28950 phase-shifted, full-bridge controller is its ability to synchronize its main oscillator to an external clock source. In this way, multiple controllers can be synchronized to improve performance criteria of the end power supply. This application report expands the details of the synchronization capability of the UCC28950, provides examples of simple circuits used to generate the proper clock inputs to the UCC28950, and gives examples of the input and output signaling that can be expected with three- and four-phase applications.

AN-2292 Designing an Isolated Buck (Fly-buck) Converter (Rev. B)
Texas InstrumentsIn many applications, one or more low-cost, simple to use, isolated power supplies working from input voltages up to 100V are needed. Traditional solutions use flyback converters to generate this bia
Digital PLL Design Using the SN54/74LS297 (Rev. B)
Texas InstrumentsThe SN54/74LS297 performs a first-order PLL function with a high degree of accuracy and a minimum of external components. Features include entirely digital design accuracy with varying temperatures and voltages digitally programmable bandwidth and center frequency narrow bandwidth ripple cancellation and cascading capabilities for high-order loops. This document provides a device description
TMS320TCI6482 Design Guide and Comparisons to TMS320TCI100 (Rev. B)
Texas InstrumentsThis document describes system design considerations for the TMS320TCI6482 (TCI6482). It also gives comparisons to designing with the TMS320TCI100 (TCI100) for those familiar with that device. The objective of this document is to cover system design considerations for the TCI6482. Those familiar with the TCI100 can use the comparisons to migrate a TCI100 design to the TCI6482. In some cases there
Introduction to Code Composer Studio Plugins
Texas InstrumentsA Code Composer Studio plugin allows for the extension or customization of the development and debug environment. The plugin can be a standalone Windows application or an ActiveX control. This application note describes the process of writing a plugin and includes the source for a simple plugin.
Configuring Emulation Parameters in Code Composer Studio v2.0
Texas InstrumentsThis application report describes how to configure Code Composer Studio? Integrated Development Envornment (IDE) v2.0 to work with different emulation parameters. In versions of Code Composer Studio prior to v2.0 these parameters were set through environment variables. With Code Composer Studio v2.0 and greater the environment variables have been replaced by platform-independent configure variab

Reading a 16-Bit Bus With the TMS320C5x Serial Port
Texas InstrumentsIt is possible to read data directly from a parallel bus. Each word is loaded by a signal for example /WE. In order to read this kind of word with a synchronous serial port it has to be converted in series and synchronized by a transmission clock. The solution presented in this document uses the clock signal coming from the DSP although an independent clock source could be implemented successfu

Understanding Photovoltaics and the Market Forces Behind Them
Texas InstrumentsForecasted demand in energy is expected to double through 2030 and could outstrip supply. Furthermorewith increasing energy prices in history advancements in “clean/green technologies” is creating a wave ofopportunity. The last 2 to 3 decades of improvement have made alternative energies more attractive andless expensive. Solar industry is the fastest growing segment in the alternative ene
Wavelet Transforms in the TMS320C55x
Texas InstrumentsWavelets have been developed to analyze the frequency components of a signal according to a scale. They provide more information than the Fourier transform for signals which have discontinuities or sharp spikes. This application report briefly presents the history of the wavelet starting with Fourier and describes the implementation of the wavelet transform using filter banks in the image pr
Building IOM-Compliant Drivers from the DCP Tool
Texas InstrumentsThe input/output mini-driver (IOM) is the standard driver model for Texas Instruments' DSP/BIOS™ operating system. A driver built on this model can be easily and efficiently tied to the software interrupt (SWI) and task (TSK) threads that are used in the DSP/BIOS scheduler via the BIOS transport mechanisms of stream input/output (SIO) and pipe (PIP) modules. This application report shows how
Switch Gains Accurately with the INA120
Texas InstrumentsIntegrated circuit instrumentation amplifiers are used in a wide variety of applications such as medical instruments data acquisition systems and thermocouple signal conditioners. Many such applications require the gain to be switched to accommodate a variety of input signals and/or wide-ranging signal levels. The INA120 instrumentation amplifier meets this requirement as well as making it simple
