TAS5010-5112F2EVM Application Report

The problems with self reset of current transformers for unipolar pulse applications can be overcome with simple forced-reset techniques derived from magnetic amplifiers. Duty factors above 90% are achievable with these techniques. This design note describes a circuit configured for forced reset and a configuration that generates a negative voltage from the current transformer.

This application report explains different aspects of selecting analog-to-digital and digital-to-analog data converters for Software-Defined Radio (SDR) applications. It also explains how ADS61xx ADCs and the DAC5688 from Texas Instruments fit properly for SDR designs.

Analog techniques have dominated signal processing for years, but digital techniques are slowly encroaching into this domain. The design of delta-sigma (DS) analog-todigital converters (ADCs) is approximately three-quarters digital and one-quarter analog. DS ADCs are now ideal for converting analog signals over a wide range of frequencies, from DC to several megahertz. Basically, these converters consist of an oversampling modulator followed by a digital/ decimation filter that together produce a high-resolution data-stream output.

This two-part article will look closely at the DS ADC’s core. Part 1 will explore the basic topology and function of the DS modulator, and Part 2 will explore the basic topology and function of the digital/decimation filter module.

This application report presents a solution to control a permanent magnet synchronous motor (PMSM) using the TMS320F2837x microcontrollers. TMS320F2837x devices are part of the family of C2000 microcontrollers, which enables the cost-effective design of intelligent controllers for three phase motors by reducing system components and increasing efficiency. With these devices, it is possible to realize far more precise digital vector control algorithms like the field orientated control (FOC). This algorithm’s implementation is discussed in this document. The FOC algorithm maintains efficiency in a wide range of speeds and takes into consideration torque changes with transient phases by processing a dynamic model of the motor.

This application report covers the following:

• A theoretical background on field oriented motor control principle
• Incremental build levels based on modular software blocks
• Experimental results

TPS54A20 Introduction to the Series Capacitor Buck Converter

This application report demonstrates how to use the on-chip temperature sensors for junction temperature monitoring. Junction temperature monitoring is the only recommended use for these on-chip temperature sensors.

At the center of every application is the need for memory. With limited on-chip processor memory, external memory serves as a solution for large software systems and data storage, and an unstable exte

The power dissipation in a LCD gate-driving circuit is shared between the level shifter output stages and the parasitic components in the display. The dynamic characteristics of the level shifter output stage and the parasitic component values are frequently unavailable. Thus it is often difficult to estimate the power dissipation. This application note presents a method to evaluate the power diss

This bulletin describes three techniques for making a precision FVC using a VFC. The standard technique has high precision but high ripple or slow settling. Adding an output filter can improve the settling-time ripple trade-off but adds error. A third new technique can eliminate ripple from the FVC output and improve settling time by more than 1000/1 as compared to the conventional FVC. Moreove

Video Designs Using High-Speed Amplifiers

Normally the output voltage of a switching power supply is higher than the error amplifier reference and so a simple resistive divider between the output voltage and ground at the non-inverting input of the PWM error amplifier is all that is required to set the regulation voltage. However when the output voltage is less than the error amplifier reference voltage the feedback voltage must be div
