Analysis and Design of Modified Half-Bridge Series-Resonant Inverter With DC-Link Neutral-Point-Clamped Cell Abstract? A modified half-bridge (HB) resonant inverter topology with a dc-link neutral-point-clamped cell is pro-posed. A pseudo asymmetrical voltage-cancellation PWM method and a control strategy are introduced. The proposed topology can maximize the inverter output power factor, and minimize variations in the switching…

ANFIS Based Add-on Controller for Unbalance Voltage Compensation in Low Voltage Microgrid Abstract-This paper presents an adaptive add-on controller for the unbalance voltage compensation in low voltage microgrid (LVMG) constituting multiple voltage source converters (VSC) based distributed generation. Since, the VSC based LVMG is almost inertia-less system and any kind of load variations have very…
Automatic Detection and Segmentation of Crohn?s Disease Tissues From Abdominal MRI Abstract?We propose an information processing pipeline for segmenting parts of the bowel in abdominal magnetic resonance images that are affected with Crohn’s disease. Given a magnetic resonance imaging test volume, it is first oversegmented into supervoxels and each supervoxel is analyzed to detect…
Autonomous Power Control and Management Between Standalone DC Microgrids Abstract-Renewable integrated DC Microgrids(DCMGs)are gaining popularity by feeding remote locations in qualitative and quantitative manner. Reliability of autonomous DC microgrids (ADCMG) depend on battery capacity and size due to stochastic behavior of renewables. Over charging and discharging scenarios compel the microgrid into insecure zone. Increasing the…
