Design and Development of Low Torque Ripple Variable-Speed Drive System With Six-Phase Switched Reluctance Motors [PDF]
, 2018 Switched reluctance motor (SRM) drives conventionally use current control techniques at low speed and voltage control techniques at high speed. However, these conventional methods usually fail to restrain the torque ripple, which is normally associated ...

A GaN-based wireless power and information transmission method using Dual-frequency Programmed Harmonic Modulation [PDF]
, 2020 Information transmission is often required in power transfer to implement control. In this paper, a Dual-Frequency Programmed Harmonic Modulation (DFPHM) method is proposed to transfer two frequencies carrying power and information with the single ...

LLC Resonant Converter as a Current Source Using Simple Trajectory Control
Energies, 2023 This paper discusses a simple method for controlling an LLC resonant DC-DC converter using a state space trajectory based on a linear combination of the voltage across the capacitor and the current through the inductance in the series resonant tank.

Control of a resonant d.c.-link converter for a.c. motor drives [PDF]
Modeling, Identification and Control, 1992 This paper presents the control of the resonant d.c.-link converter for a.c. motor drives. This is a low loss converter with higher efficiency than a conventional PWM converter, but it requires complex control.

One-cycle control of switching converters [PDF]
, 1995 A new large-signal nonlinear control technique is proposed to control the duty-ratio d of a switch such that in each cycle the average value of a switched variable of the switching converter is exactly equal to or proportional to the control reference in

Pediatric Blood &Cancer, EarlyView.ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.
