A non-isolated quasi-Z-source-based high-gain DC-DC converter
Mahmood, Arshad; Zaid, Mohammad; Khan, Shahrukh; Siddique, Marif Daula; Iqbal, Atif; Sarwer, Zeeshan... more authors ... less authors ( John Wiley and Sons Ltd , 2022 , Article)To overcome the problems associated with Z-source-based DC-DC converters, a quasi-Z-source (QZS)-based high-gain DC-DC boost converter with switched capacitors is proposed in this work. Z-source-based DC-DC converters have ... -
A switched-capacitor multilevel inverter topology employing a novel variable structure nearest-level modulation
Sarwer, Zeeshan; Siddique, Marif Daula; Sarwar, Adil; Zaid, Mohammad; Iqbal, Atif; Mekhilef, Saad... more authors ... less authors ( John Wiley and Sons Ltd , 2021 , Article)This article introduces a nine-level switched-capacitor multilevel inverter with twice voltage boosting feature. It also aims at proposing a novel variable structure nearest-level modulation scheme that has been implemented ... -
A transformerless high gain dc-dc boost converter with reduced voltage stress
Zaid, Mohammad; Khan, Shahrukh; Siddique, Marif Daula; Sarwar, Adil; Ahmad, Javed; Sarwer, Zeeshan; Iqbal, Atif... more authors ... less authors ( John Wiley and Sons Ltd , 2021 , Article)In this paper, a modified and improved high gain dc-dc boost converter is proposed. The converter has utilized two voltage multiplier cells (VMCs) comprising switched capacitors (SC) and switched inductors (SL) to increase ... -
An improved asymmetrical multilevel inverter topology with reduced semiconductor device count
Sarwer, Zeeshan; Siddique, Marif Daula; Iqbal, Atif; Sarwar, A.; Mekhilef, Saad ( John Wiley and Sons Ltd , 2020 , Article)Background: Multilevel Inverters have become a viable alternative to two-level inverters because of their superior power quality, however, the increase in number of switches with their corresponding voltage stress, and dc ... -
Asymmetrical multilevel inverter topology with low total standing voltage and reduced switches count
Bin Arif, M. Saad; Sarwer, Zeeshan; Siddique, Marif Daula; Md. Ayob, Shahrin; Iqbal, Atif; Mekhilef, Saad... more authors ... less authors ( John Wiley and Sons Ltd , 2021 , Article)This paper presented an improved asymmetrical multilevel inverter module with reduced switches count. The basic module is capable of producing 15 level outputs with four dc sources and 10 switches. The proposed topology ... -
Seven-level switched-capacitor based multilevel inverter with lesser number of power electronic components and reduced voltage stress
Sarwer, Zeeshan; Siddique, Marif Daula; Iqbal, Atif; Sarwar, A.; Rahman, K.; Mekhilef, Saad... more authors ... less authors ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)This paper puts forward a seven-level switched-capacitor multilevel inverter (7L-SCMLI) with boosting features. The main features of the proposed structure are the use of reduced number of switches, lesser value of total ...
