Novel Level-Shifted PWM Technique for Equal Power Sharing among Quasi-Z-Source Modules in Cascaded Multilevel Inverter
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
Phase-shifted pulsewidth modulation (PS-PWM) is a well-known switching technique for quasi-Z-source (qZS)-based cascaded multilevel inverters (qZS-CMI). PS-PWM ensures equal power distribution (among operating modules) and ...
A Single DC Source-Based Three-Level Inverter Topology for a Four-Pole Open-End Winding Nine-Phase PPMIM Drives
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
This article proposes a three-level inverter topology for nine-phase pole phase-modulated induction motor (PPMIM) drives by using the two identical voltage profile coils (IVPC) of a four-pole stator winding. In general, ...
Novel Level Shifted PWM Technique for Unequal and Equal Power Sharing in Quasi Z-Source Cascaded Multilevel Inverter for PV Systems

Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
Conventional phase-shifted pulsewidth modulation (PS-PWM) is a usual switching technique for Z-source/quasi-Z-Source (qZS)-based cascaded multilevel inverters (CMIs) (qZS-CMIs). The PS-PWM scheme causes higher switching ...
A Hybrid Multilevel Inverter Scheme for Nine-Phase PPMIM Drive by Using Three-Phase Five-Leg Inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
In pole-phase modulation, the phase order is coming down by pole ratio times in high pole mode, which results in the higher magnitude of spatial harmonics as well as higher torque ripple. In this article, the available ...
Modelling, analysis, and implementation of a switched-inductor based DC/DC converter with reduced switch current stress

Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
Recently, switched inductor (SI) and switched capacitor techniques in dc-dc converter are recommended to achieve high voltage by using the principle of parallel charging and series discharging of reactive elements. It is ...
Non-Isolated DC-DC Power Converter with High Gain and Inverting Capability
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
As the voltage gain of converter increases with the same ratio, the current gain also increases, this increase in current gains will affect the size of the input and the output capacitor. To reduce the ripple in the input ...
