How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Chandra Shekar Thelukuntla completed PhD at the Department of Electrical Engineering, Indian Institute of Technology Delhi. Chandra Shekar does research in Power Electronics. The most recent publication is 'Adaptive tuning algorithm for single-phase Z-source inverters.'
This study proposes an adaptive tuning algorithm for dynamic adjustment of the saturation limits for the shoot-through duty ratio (STDR) and modulation index of a Z-source inverter. This adaptive tuning is crucial in Z-source inverter applications where wide fluctuations in dc source voltage are expected. Even though a standalone application is cho...
This paper presents a proportional plus resonant controller based single-phase Z-source inverter with LCL-filter for a utility connected system. Proportional plus integral (PI) control of ac systems has steady state error and can be eliminated by a resonant controller which incorporates model of input signal in its loopgain, by internal model princ...
This paper presents a single-phase Z-source inverter as a power conditioning system for a grid-connected system. Z-source inverter is a single-stage topology that has buck-boost feature, which is possible because of additional shoot through state introduced in zero state of the conventional inverter pulse width modulation and provides desired outpu...
This paper presents a Z-source inverter as a power conditioning system, which has bucking and boosting feature, for a single-phase stand-alone ac system. The bucking as well as boosting feature is possible because of additional shoot through state introduced in zero state of the conventional inverter pulse width modulation. A small DG system requir...
