Volterra Models for Digital PWM and Their Inverses
(Institute Of Electrical And Electronics Engineers, 2015-10)
In an all-digital class-D audio amplifier each signal sample is mapped into a pulse using digital pulse-width-modulation (PWM), and this intrinsically generates nonlinear distortion. This article develops discrete-time ...
Performance of a Zero Average Dynamics-controlled buck converter using different pulse-width modulation schemes
(Wiley, 2015-04)
The response of a digital Zero Average Dynamics (ZAD)-controlled buck converter under the variation of its intrinsic parameters as well as the pulse-width modulation signal is studied in detail. The multiparameter analysis ...
Frequency Analysis of PWM Inverters With Dead-Time for Arbitrary Modulating Signals
(Institute Of Electrical And Electronics Engineers, 2014-06)
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 ...
The ZVS-PWM commutation cell applied to the DC-AC converter
(1997-12-01)
This paper presents the analysis of a dc-ac converter using a zero-voltage-switching (ZVS) commutation cell. First, we show the cell applied to the buck converter. The stages of operation are presented along with the main ...
Adaptive Dead-Time Compensation for Grid-Connected PWM Inverters of Single-Stage PV Systems
(Institute of Electrical and Electronics Engineers, 2013-06)
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) ...
Table-based PWM for all-digital RF transmitters
(John Wiley & Sons Ltd, 2019-02)
In this paper, a novel pulse-width modulator (PWM) for an all-digital PWM transmitter based on switching amplification is presented. In this approach, each symbol is represented by a sequence of pre-computed PWM pulse ...
PBC Approach for SMES Devices in Electric Distribution Networks
(Institute of Electrical and Electronics Engineers, 2018-12)
This express brief presents a nonlinear active and reactive power control for a superconducting magnetic energy storage (SMES) system connected in three-phase distribution networks using pulse-width modulated current-source ...
Model-predictive-control-based capacitor voltage balancing strategies for modular multilevel converters
(IEEE, 2019)
This paper presents two capacitor voltage balancing (CVB) strategies for modular multilevel converter (MMC) applications. Both balancing schemes are based on model predictive control and are designed to efficiently solve ...
The ZVS-PWM commutation cell applied to the DC-AC converter
(1997-12-01)
This paper presents the analysis of a dc-ac converter using a zero-voltage-switching (ZVS) commutation cell. First, we show the cell applied to the buck converter. The stages of operation are presented along with the main ...
Symbol-rate Baseband Signal Model for RF Pulse-Width Modulation Transmitters
(Institute of Electrical and Electronics Engineers, 2021-06)
Aiming to shed light on the operation of fully-digital transmitters, we present the first symbol-rate baseband model that makes explicit the inter-symbol interference introduced by the RF pulse-width modulation (RF-PWM). ...
