Smart meters not only have bi-directional communication, bi-directional metering, event recording, multi-tariffs, etc., but also have important load control functions. The load control function means that the meter is designed with high quality relays inside, which can be switched on and off according to the requirements to achieve the purpose ...
An adaptive hysteresis current and voltage control technique for controlling Unified Power Quality Conditioner (UPQC) is proposed in this paper. The novelty of the proposed method is the series and shunt active power filters (APF) present in the UPQC has been controlled by the separate adaptive ...
The output voltages of the proposed cycloconverters are controllable step–up and step–down in nature with duty cycle control of switching regulators. Total Harmonic Distortion (THD) of the input current of the proposed circuits is minimised by input filters before the rectifier. Input power factor and efficiency of the circuits are high. Open ...
It includes the modelling of proton electrolyte membrane fuel cell and the power conditioning unit interfacing the fuel cell to the utility grid with proper power flow control. ...
This paper presents a hybrid active power filter for harmonics and reactive current compensation while reducing the rating of active power filter. ...
This paper presents a new transformerless series hybrid active power filter topology (TL-SHAPF). The active filter is in series with a capacitor. ...
Active power filters are widely accepted and implemented as a reliable means for solving power quality problems and supplying clean power to the end user. In this paper, a novel three-phase shunt active filtering algorithm is proposed and simulated. The control algorithm is implemented in hardware using simple ...
A comparative analysis of Cuk converter is also presented in both modes of operation of DCM and CCM from point of view of steady-state and dynamic behaviour, power quality, simplicity, control technique, device rating and converter size. It is observed that CCM is most suitable for higher power applications in which it requires a ...
