Virtual flux oriented sensorless direct power control of qzs inverter connected to grid for solar pv applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Impedance source inverters (Z-source and Quazi-Z-source (QZS)) are the promising converter topologies in the future generation because of the buck, boost and buck-boost modes of operation. In this paper, three phase voltage ...
Novel voltage balancing algorithm for single-phase cascaded multilevel inverter for post-module failure operation in solar photovoltaic applications
(
Institution of Engineering and Technology
, 2019 , Article)
Four cascaded quasi-impedance source inverter (qZSI) modules are required for achieving nine-level output voltage waveform. In case of one module failure, number of levels in output voltage are reduced to seven. This leads ...

, 2019 , Article)
High efficiency is an important requirement from DC-DC converter in DC microgrid system when integrated with renewable energy sources. This study proposes a new tri-switching state non-isolated high gain boost converter ...
A New Variable Frequency Control of 49-Level Cascaded Packed U-Cell Voltage Source Inverter
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Requirement of large number of levels with lower number of switching devices has made asymmetrical converters more popular than the symmetrical ones. Asymmetrical cascaded multilevel inverters (ACMLI) can achieve high ...
Hardware implementation of a new single input double output L-L converter for high voltage auxiliary loads in fuel-cell vehicles
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Typically, the fuel cell output voltage magnitude is low and a series connection of several fuel cells is not a practical solution to achieve high voltage for vehicular applications. Therefore, DC-DC converter with a high ...
Novel level-shifted PWM technique for cascaded multilevel quasi-impedance source inverter
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
In a multilevel quasi-impedance source inverter (qZSI), phase-shifted carrier pulsewidth modulation (PS-PWM) is the most popular modulation method as it offers advantages such as simple implementation and evenly powered ...
