Reference generator for voltage controlled power conditioners
(2011-12-28)
Voltage reference generation is an important issue on electronic power conditioners or voltage compensators connected to the electric grid. Several equipments, such as Dynamic Voltage Restorers (DVR), Uninterruptable Power ...
Practical evaluation of different modulation techniques for current-controlled voltage source inverters
(INST ENGINEERING TECHNOLOGY-IET, 1996)
The quality of the current waveform generated by a current-controlled, voltage source inverter, depends basically on three factors: (a) the switching frequency of the PWM modulator; (b) the type of current waveform being ...
Métodos para correção das distorções da forma de onda secundária causadas pela saturação de transformadores de corrente para serviço de proteção
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2011-02-18)
This work aims to evaluate the performance of some methods used to detect and
correct the distorted portions of the secondary current signal waveform, which occur due to
the core saturation of current transformers. Such ...
Dead-Time Distortion Shaping
(Institute of Electrical and Electronics Engineers, 2019-01)
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 ...
