Torque Ripple Reduction for Switched Reluctance Motor with Optimized PWM Control Strategy
Energies, 2018 The high current ripple and torque ripple are the main drawbacks of the switched reluctance motor (SRM) since the nonlinearity and double saliency, which limits its applications. In order to eliminate the current variation and torque ripple, an optimized

Sliding Mode Controller for Parameter-Variable Load Sharing in Islanded AC Microgrid
Energies, 2022 Controlling voltage, frequency, and current in an islanded microgrid is a challenging problem because the distributed generation sources, stochastic and intermittent in nature, are not connected to the main electricity network to provide stable and clean

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Characterizing stressful events reported by childhood cancer survivors experienced throughout the lifespan may help improve trauma‐informed care relevant to the survivor experience. Methods Participants included 2552 survivors (54% female; 34 years of age) and 469 community controls (62% female; 33 years of age) from the St.

Exploring Damping Effect of Inner Control Loops for Grid-Forming VSCs
IEEE Open Journal of Power ElectronicsThis paper presents an analytical framework to evaluate the damping contributed by inner control loops in grid-forming voltage-source converters. First, an impedance model is developed to characterize the dynamics of three types of inner loops, with the ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...
