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 ...
Implementação de um modulador PWM para inversor multinível ponte H em cascata de 7 níveis em FPGA
(Universidade Estadual Paulista (Unesp), 2022-03-18)
This paper presents the implementation in a FPGA of a PWM modulation using different PWM modulation techniques for single-phase seven level cascaded H-bridge inverter. For this, the working principle of this inverter and ...
Control of three-phase PWM boost rectifiers using proportional-resonant controllers
(2018-06-25)
Voltage-oriented vector control (VOC) using proportional-integral controllers is an attractive control method for three-phase PWM rectifiers, due to relative ease of implementation, being one of the most used methods. ...
Open-loop VAr compensator for industrial applications, using a single PWM pattern
(IEE-INST ELEC ENG, 1997)
The authors present the analysis of an open-loop, three-phase static VAr compensator (SVC) based on a voltage source inverter, using only one fixed pulse width modulation (PWM) pattern. The VAr generation is controlled by ...

Baseband model for uniformly sampled RF-PWM
(Institute of Electrical and Electronics Engineers, 2020-03-12)
A baseband model for a polar RF modulator based on uniform sampling (US) pulse width modulation (PWM) is presented. RF-PWM allows to encode a complex baseband signal (amplitude and phase) into the pulse width and pulse ...
