The three-phase rectifier based on traditional PID control algorithm can improve its harmonic effect, and increase its power factor, but it can’t overcome the problems of selection difficulty of the PID parameters and can realize the online self-turning function of the PID parameters. In order to deal with the questions, the three phase rectifier based on neural network PID control algorithm is...

Deep learning is regarded by some as one of the most important technological breakthroughs of this decade. In recent years it has been shown that using rectified neurons, one can match or surpass the performance achieved using hyperbolic tangent or sigmoid neurons, especially in deep networks. With rectified neurons we can readily create sparse representations, which seems especially suitable f...

This article presents a simple and rather precise method for analysis and design of a transformer-coupled input rectifier with a filter capacitor, which is used as a power supply for electronic circuits. It is based on an original logarithmic equation that determines the conduction angle of the rectifier diodes as a function of the transformer equivalent resistance. This equation can replace th...

In the past few years problems like harmonic pollution or waveform distortion became more important as the load nature changed. The typical linear loads have been progressively replaced by non-linear ones, where rectifier systems have a great importance. A wide variety of industrial applications such as variable speed drives and most of power electronics’ converters use uncontrolled rectifiers ...

A boost converter which employs an isolated active snubber to reduce the losses caused by the reverserecovery characteristic of the boost rectifier and the turnon discharge loss of the output capacitance of the boost switch is described. The proposed isolated active snubber consists of a coupled inductor, clamp capacitor, and ground-referenced N-type MOSFET. The performance of the proposed conv...

This paper deals with the control of three phase PWM rectifier model using SVM based current controller. In many power electronics control applications the rectifier plays vital role during AC/DC power conversion. The SVM-based HCC scheme is simulated using MATLAB simulink. The technique combines the best features of the SVM and HCC techniques. The controller determines a set of state space vec...

This paper proposes a novel simplified brushless wound field synchronous machine (BL-WFSM) topology based on an uncontrolled three-phase rectifier. The output of the rectifier is injected into common point star-connected armature winding. arrangement develops MMF consisting two components: fundamental MMF, which rotating in nature, and harmonic pulsating magnetic field, induces current speciall...

The bioelectrical properties and resulting metabolic demands of electrogenic cells are determined by their morphology and the subcellular localization of ion channels. The electric organ cells (electrocytes) of the electric fish Eigenmannia virescens generate action potentials (APs) with Na(+) currents >10 μA and repolarize the AP with Na(+)-activated K(+) (KNa) channels. To better understand t...

Electric fields impact cellular functions by activation of ion channels or by interfering with cell membrane integrity. Ion channels can regulate cell cycle and play a role in tumorigenesis. While the cell cycle may be directly altered by ion fluxes, exposure to direct electric current of sufficient intensity may decrease tumor burden by generating chemical products, including cytotoxic molecul...
