A Feedback PWM Technique Using Periodical Mean Output Error

LMI Robust Control of PWM Converters: An Output-Feedback Approach

neural classifier ensemble using error-correcting output codes: access control application

abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...

Compensation PWM Technique for Extended Output Voltage Range in Three-Phase VSI Using Three Shunt Resistors

This paper proposes a compensation PWM technique for the extension of output voltage ranges in three-phase VSI applications using three shunt resistors. The proposed technique aims to solve the dead zone, which occurs in high modulation indexes. In the dead zone, two phase currents cannot be sampled correctly, so that the three-phase VSI cannot be operated up to the maximum output voltage. The ...

Controlling Analog Output From a Digital CPLD Using PWM

Although the Altera® MAX® IIZ CPLD is a digital programmable logic device, it is versatile enough to control analog systems. This white paper shows how the MAX IIZ CPLD, alone or with a few passive components, can replace a digital-to-analog converter, allowing it to drive an audio speaker and control LED intensity, motor speed, and servo position. This white paper also will explain pulse-width...

Hybrid Technique for Inverter Using PWM

A hybrid pulse width modulation (PWM) theme for the grid electrical converter is investigated, which combines the deserves of space-vector PWM (SVM) and elite harmonic elimination PWM (SHEPWM). SHEPWM is adopted at steady state, while SVM is adopted to reach higher dynamic performance at grid fault. A transition strategy between these two PWM schemes is projected, which achieves sleek and fast ...
