A fully digital algorithm to shape the spectrum of dead-time distortion in power inverters is presented. Dead-time is required to avoid short circuits of the power source by the legs of a power inverter due to the finite ...

The effect of dead-time on the spectrum of pulsewidth modulated signals is analyzed in this paper. The study is valid for arbitrary, band-limited modulating signals, extending previous results in the literature. A simple ...

This study presents a new software-based plug-in dead-time compensator for grid-connected pulsewidth modulated voltage-source inverters of single-stage photovoltaic (PV) systems using predictive current controllers (PCCs) ...

The output voltage of PWM power inverters shows harmonic distortion due to several causes; the main ones are the modulation algorithm, nonlinearities in the output filter, dead times, voltage drops across the switches and ...

This paper aims to discuss the Lacanian clinic of anorexia. Therefore, a qualitative methodology that included a literature review and a field survey was used. We consulted the main authors who study anorexia and refer to ...

Esta dissertação apresenta a modelagem, o projeto, a análise de estabilidade e o ajuste de controladores de um conversor multinível de ponte-H em cascata (CHB), operando como um filtro ativo em derivação (shunt), utilizando ...
