In this paper, we report a new 4 H-silicon carbide (SiC) lateral dual sidewall Schottky (LDSS) rectifier on a highly doped drift layer consisting of a high-barrier sidewall Schottky contact on top of the low-barrier Schottky contact. Using twodimensional (2-D) device simulation, the performance of the proposed device has been evaluated in detail by comparing its characteristics with those of th...

To efficiently supply wide-range DC voltage from a pulse-width modulation (PWM) rectifier, this paper presents a single-phase, full-wave, diode-bridge, single-ended primary-inductor converter-type (SEPIC-type) power-factor-correction (PFC) rectifier in continuous conduction mode with a sliding surface-regulated current-mode PWM controller. According to the switched-mode operation of the rectifi...

Motor drive systems based on diode-rectifier are utilised in many industrial and commercial applications due to their cost-effectiveness simple topology. However, these diode rectifier-based can be affected by power quality harmonics distribution networks. Thus, this paper investigates the impact of grid voltage operation converters with three-phase rectifier using mathematical formulation curr...

Oxide material can make transparent devices with transparent electrodes. We developed a transparent oscillator and rectifier circuits with oxide TFTs. The source/drain and gate electrodes were made by indium thin oxide (ITO), and active layer made by transparent material of IGZO (Indium Gallium Zinc Oxide) on a glass substrate. The RC oscillator was composed of bootstrapped inverters, and 813 k...

The emergence of deforming regimes is related to the proliferation of nonlinear electrical receivers. The higher harmonics of drawn currents from power systems can be evaluated using Discrete Wavelet Transform (DWT). Unlike Fast Fourier Transform (FFT), which provides only amplitude-frequency information but looses time information, DWT analyses the signal in a time-frequency domain using windo...

A versatile precision rectifier based on a current conveyor and current mirrors is presented. The proposed circuit performs positive half-wave, negative half-wave, positive full-wave, and negative full-wave rectification into a single circuit. The current-mode technique has been employed to provide the high-precision capability of the circuit. The circuit configuration is very suitable for inte...

The harmonic currents generated by the single-phase rectifier are well known. As the levels of these currents become larger, the use of power conditioners such as shunt active filters to lower the levels is becoming more attractive. In order to analyze the interaction between the condition, ac system, and rectifier it is necessary to have an accurate model of the rectifier. This paper describes...

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...
