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 ...
Design of a Multiport Microwave Modulator for Dynamic Polarization Reconfiguration
(Institute of Electrical and Electronics Engineers, 2019-05)
This paper presents a seven-port modulator capable of switching the polarization state of the transmitting signal. Similar to the six-port modulator, the proposed device modulates the carrier signal through the reflection ...
Dark I-V measurements of single cells in a photovoltaic module
(John Wiley & Sons Ltd, 2005-12)
A simple method of obtaining single cell dark I-V curves in a photovoltaic module was developed. The method does not require disassembling the module and was experimentally verified. From the dark I-V curves, the cell ...
Modulação Space Vector aplicada a inversores monofásicos e trifásicos
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2016-09-23)
This work aims to present the Space Vector modulation, geometrically illustrating its behavior. Initially, the Space Vector modulation is applied to a full-bridge single-phase inverter and some important concepts about the ...
A new family of zero-current-switching PWM converters and a novel HPF-ZCS-PWM boost rectifier
(Institute of Electrical and Electronics Engineers (IEEE), 1999-01-01)
A new family of direct current (DC) to DC converters based on a zero current switching pulse width modulated (ZCS-PWM) soft commutation cell is presented. This ZCS-PWM cell is consists of two transistors, two diodes, two ...
Low-cost PWM speed controller for an electric mini-baja type vehicle
(2007-01-01)
This paperwork presents a Pulse Width Modulation (PWM) speed controller for an electric mini-baja-type car. A battery-fed 1-kW three-phase induction motor provides the electric vehicle traction. The open-loop speed control ...
