A New Three-Level Split-Inductor T-Type Inverter

A New Three-Level Split-Inductor T-Type Inverter

IEEE Energy Conversion Congress and Exposition, ECCE

作者： Lucas Vinicius de Araújo Gomes Montiê Alves Vitorino Maurício Beltrão de Rossiter Corrêa Graduate Program in Electrical Engineering (PPgEE–COPELE) Industrial Electronics and Machine Drive Laboratory (LEIAM) Federal University of Campina Grande (UFCG)

Some of the key requirements and trends in power electronics in recent years include improving efficiency as well as providing a energy quality while using a converter with high power density and long lifetime. Following these tendencies, multilevel T-type converters have the potential to improve the efficiency and performance of power conversion systems, especially in the renewable energy industry. A new multilevel converter with split-inductors is proposed, that offers dead-time elimination, shoot-through protection, ringing suppression and improved efficiency. Since the split-inductors are always connected in series with the switches, the protection against shoot-through is achieved by regulating the circulating current, eliminating the need for dead-time. Simulation and experimental results were shown to prove the functionality of the proposed converter.

This paper proposes a reconfiguration for a single-phase, double conversion uninterruptible power supply (UPS). With the addition of two static switches to the original circuit, the UPS mitigates the ripple in the current, through battery discharge performed by two legs. Other than these switches, the circuit topology is preserved. The preliminary results show a satisfactory level of ripples for the inductor current and suitable power quality for the output voltage. © 2023 IEEE.

作者： Vitor Freire Bezerra Rhavél Batista Morais Montiê Alves Vitorino Graduate Program in Electrical Engineering (PPgEE-COPELE) Industrial Electronics and Machine Drive Laboratory (LEIAM) Federal University of Campina Grande (UFCG)

The large industries that work with high power demand increasingly want to optimize their production lines. In this context, several studies and research about the multi-level power converts have been realized in last years, as they have several advantages when compared to traditional two-level topologies: better harmonic performance, filters reduction, lower components voltage stress and higher power process capability. The present work proposes a Cuk DC-DC converter composed of multilevel flying capacitor asymmetric totem-pole switching cell. This structure is achieved by replacing one leg of switch/diode of the traditional two-level asymmetric totem-pole cell by a similar multilevel flying capacitor cell. This work presents a brief analysis of the operation of the proposed converter, as well as the control strategy to keep the output voltage at the desired value and contains simulation results to validate the theoretical approach.

Three-phase Multilevel NPC Rectifier with High-Frequency Pulsating DC-bus, Reduced Number of Switches and Galvanic Isolation with Transformer with Center Tap

IEEE Energy Conversion Congress and Exposition, ECCE

作者： Yuri Cavalcanti Ailton Do Egito Dutra Montiê Alves Vitorino Graduate Program in Electrical Engineering (PPgEE–COPELE) Industrial Electronics and Machine Drive Laboratory (LEIAM) Federal University of Campina Grande (UFCG)

This paper proposes a three-phase three-level AC/DC converter with reduced number of controlled switches and high-frequency DC-bus based on NPC (Neutral Point Clamped) topology, for unidirectional power flow applications. Galvanic isolation is reached by using a center tap transformer, which requires only a full-bridge at it primary side. No bulky electrolytic capacitors are needed on the DC-bus, in contrast to conventional multilevel topologies. A PWM strategy with carriers arranged in alternating phase opposition (PWM-APOD) is used to operate the proposed converter. The applied PWM technique is able to operate the converter stage on the AC side with only two switches commuting per switching period. The switches of the isolated pulsating DC/DC converter are commutated with half the switching frequency of the converter on the AC side. A dual-loop control strategy with PI voltage and PI resonant current controllers is adopted to ensure reference load voltage and almost sinusoidal grid currents. Simulation and experimental results are presented to validate the proposed converter operation.

Nowadays multilevel converters have been widely adopted in low and medium power DC-DC conversion systems, especially for automotive applications and renewable energy systems. However, the increase in the number of components and the complexity of the control also complicate the modeling and control of these converters. A dynamic model will be detailed, studied, and used to illustrate the properties of the SEPIC DC-DC converter with three-level flying capacitor switching cell. The model’s applications include, but are not limited to, controller analysis, design for load voltage regulation, and flying capacitor voltage balancing. Both simulations and experimental results are provided to verify the principle of operation.

Buck-boost current-source based converters are attractive for applications in electric vehicles (EVs) due to several inherent benefits regarding high-power charging. However, methods are still needed to increase the efficiency of these converters. This paper covers a mathematical analysis of the three-phase buck-boost rectifier with reactive power capability and shows its equation and operating conditions for a wide range of power factors. In addition, the control strategy based on space vector modulation (SVM) is presented in detail, as well as the passive elements design. Experimental results show that the converter modulated by SVM is more efficient in terms of switching losses compared to scalar modulation.

In this paper, dual Vienna rectifiers are proposed for Wind Energy Conversion System (WECS) applications with Open-End Winding (OEW) Permanent Magnet Synchronous Generator (PMSG). Due to the reduced number of controlled switches, the proposed topologies have reduced costs and high reliability. Besides, they provide a better power quality using the same number of controlled switches than conventional structures presented in the literature, making them very attractive options for industry applications. The system model, space vector modulation, and control strategy are given. Simulation results are provided in order to validate their performance and feasibility. © 2020 IEEE.

This paper proposes a new three-phase AC-DC isolated rectifier topology with zero-voltage switching capability. The structure is obtained by adding a single transformer that is excited by the common-mode voltage generated by the three-leg converter. It is presented an analysis of the converter's operation, covering modulation concepts and control strategies to maintain the output voltage at the desired value and guarantee unity power factor and very low total harmonic distortions. The experimental results is obtained over a 1kW prototype which provides a power factor of 0.99 and efficiency of 91.7%. The full results are presented and discussed to validate the proposed converter topology.
