This paper addresses a basic control issue in switched reluctance motor (SRM) drives—the production of a ripple-free torque. Simple and largely model-independent conventional supply waveforms are not able to satisfy this requirement. The goal of this paper is to improve SRM dynamical performance by compensating for motor nonlinearities, while maintaining the robustness of conventional methods. ...

This paper presents a new Unified PowerQuality Conditioning System (MCUPQC),capable of simultaneous compensation for voltage and current in multi-bus/multi-feeder systems. By using one shunt Voltage-Source Converter(VSC) and two or more series VSCs the configuration is made. The system can be applied to adjacent feeders to compensate for supplyvoltage and load current imperfections on the main ...

A low carbon, high efficiency and high quality power supply scheme for Distributed Generation (DG) in a micro-grid is presented. A three-phase, four-leg DG grid-interfacing converter based on the improved structure of a Unified Power Quality Conditioner (UPQC, including a series converter and a parallel converter) is adopted, and improved indirect and direct control strategies are proposed. It ...

This paper presents a new control scheme of voltage source active filter (AF) which compensates simultaneously the harmonics and reactive power of non-linear loads. The reference compensating currents are estimated from computed reference supply currents and sensed load currents. Reference supply currents are estimated using active power of the load and the AF. A hysteresis or carrier based PWM...

Abstract: A novel low-dropout (LDO) regulator without external capacitor featuring with fast transient response and low-power dissipation for System-On-Chip (SOC) is proposed in this paper. By introducing an auxiliary feedback path to splits the poles without using a miller compensating scheme, the proposed LDO achieves fast transient response and high stability under all operating conditions. ...

This paper presents a new method to compensate the nonlinearity for matrix converter drives using disturbance observer. The nonlinearity of matrix converter drives such as commutation delay, turn-on and turn-off time of switching device, and on-state switching device voltage drop is modeled by disturbance observer and compensated. The proposed method does not need any additional hardware and of...

-. The beam-beam interaction with a crossing angle and with a compensating crab angle is simulated and treated partially analytically. The crab angle is obtained by transversely deflecting cavities in one case and by a dispersion in the accelerating cavities in another case. Resonances which are excited by the action of the crab cavities are investigated. Tolerances for the cavity voltage and f...

Single-loop current sensorless control allows for abolishing of the instantaneous measurement in system using only a single loop with voltage feedback to stabilise DC-bus voltage. This approach eliminates sensors circuit, benefiting from saving space on printed circuit board and minimising power dissipation circuitry. paper focuses single-loop applied bidirectional three-phase four-wire three-l...
