A Transformerless Intelligent Power Substation: A three-phase SST enabled by a 15-kV SiC IGBT
Krishna Mainali,Awneesh Tripathi,Sachin Madhusoodhanan,Arun Kadavelugu,Dhaval Patel,Samir Hazra,Kamalesh Hatua,Subhashish Bhattacharya +7 more
TL;DR: The solid-state transformer (SST) is a promising power electronics solution that provides voltage regulation, reactive power compensation, dc-sourced renewable integration, and communication capabilities, in addition to the traditional step-up/stepdown functionality of a transformer as mentioned in this paper.
Journal ArticleDOI
Design Considerations of a 15-kV SiC IGBT-Based Medium-Voltage High-Frequency Isolated DC–DC Converter
Awneesh Tripathi,Krishna Mainali,Dhaval Patel,Arun Kadavelugu,Samir Hazra,Subhashish Bhattacharya,Kamalesh Hatua +6 more
TL;DR: In this paper, a dual active bridge (DAB) is a zero-voltage switching (ZVS) high-power isolated dc-dc converter with parasitic capacitances.
Journal ArticleDOI
Modeling and Analysis of Stator Interturn Fault Location Effects on Induction Machines
Dhaval Patel,Mukul C. Chandorkar +1 more
TL;DR: A simple yet accurate stationary reference frame q-d-0 model of SIT-faulted induction machine, including the fault location parameter, is developed and the steady-state analysis indicates that the inclination of the current vector locus and the phase angle of the negative-sequence current phasor are the strong indicators of the SIT fault location.
Journal ArticleDOI
Three-Dimensional Flux Vector Modulation of Four-Leg Sine-Wave Output Inverters
TL;DR: Experimental results indicate the effectiveness of the modulator and control system in providing balanced voltages at the output of the LC filter even under highly unbalanced conditions with nonlinear loads.
