Multilevel inverter employing cascaded transformers

IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat. No.03CH37468), 2004
This paper presents a novel multilevel inverter employing series-connected transformers to reduce the harmonics of output voltage. The proposed inverter consists of three full-bridge modules and their corresponding transformers. Continuous output voltage levels can be generated from a suitable selection of turn-ratio of transformer.

Development of Cascaded Multilevel Inverter Topology

2020 IEEE First International Conference on Smart Technologies for Power, Energy and Control (STPEC), 2020
In this work, a single phase cascaded multilevel inverter topology is proposed which will work in both symmetrical and asymmetrical magnitude of DC sources voltage. Proposed topology has two main parts i.e basic unit and polarity reversal unit. This topology is simple to understand and can be easily cascaded for generating more level in output voltage.

Cascaded multilevel inverters fault control

International Aegean Conference on Electrical Machines and Power Electronics and Electromotion, Joint Conference, 2011
This paper proposes a new control method to increase cascaded multilevel inverters (GVfl) efficiency at faulty condition. The influence of most probability fault on GVfl with carrier based pulse width modulation (CBPWM) is investigated and the maximum output voltage is derived without elimination of faulty power cell.

Analysis of Cascaded multilevel inverter

India International Conference on Power Electronics 2010 (IICPE2010), 2011
There is a new control strategy to control Cascaded multilevel converters in a multi-string configuration for single phase grid connected systems. This topology generates high quality output current under any circumstances specifically in partial shading, while tracking the MPP of each string independently. The topology does not consist of any extra DC-

Cascaded multilevel inverter for Hybrid Electric Vehicles

India International Conference on Power Electronics 2010 (IICPE2010), 2011
Hybrid Electric Vehicle (HEV) is an emerging technology in the modern world because of the fact that it mitigates environmental pollutions and at the same time increases fuel efficiency of the vehicles. Multilevel inverter controls electric drive of HEV of high power and enhances its performance which is the reflection of the fact that it can generate ...

Control of Cascaded Multilevel Inverters

IEEE Transactions on Power Electronics, 2003
A new type of multilevel inverter is introduced which is created by cascading two three-phase three-level inverters using the load connection, but requires only one dc voltage source. This new inverter can operate as a seven-level inverter and naturally splits the power conversion into a higher-voltage lower-frequency inverter and a lower-voltage ...

Cascaded Transformers-Based Multilevel Inverters With NPC

IEEE Transactions on Industrial Electronics, 2022
The basic structure and generalization of two cascaded transformer multilevel inverters (CTMIs) are proposed in this paper. Such configurations are based on cascaded symmetrical transformers coupled to two-level (2L) legs and three-level (3L) neutral-point clamped (NPC) legs. One configuration has a shared 2L leg, connected to all transformers.

A Novel Hybrid Cascaded Multilevel Inverter

2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018
This paper introduces a novel hybrid cascaded multilevel inverter. It is a series connection of two asymmetrical inverters, compared to the traditional cascaded multilevel inverter, the proposed cascaded inverter can produce more output levels using the same switches, the most number of output levels and modulation strategy are analyzed.

Optimal Structures for Cascaded Multilevel Inverter

International Journal of Computing Algorithm, 2017
The general function of a multilevel inverter is to synthesize a desired output voltage from several levels of dc voltages as inputs. In order to increase the steps in the output voltage, a new H- bridge topology is recommended which benefits from a series connection of several sub-multilevel inverters. In addition, for producing an output voltage with
