In this paper, a reconfigurable, low power four quadrant memristor and carbon nanotube field effect Transistor (CNFET) based analog multiplier is proposed. The circuit is verified by extensive HSPICE simulations using experimentally verified memristor and Stanford CNFET models that have been calibrated for 90% accuracy at the 32nm technology node. The proposed multiplier has an input range of ±...
This paper demonstrates the use of quasi-floating gate MOSFET (QFGMOS) in the design of a current-to-voltage converter that operates for the input current range of 0 to 50?A. The workability of the circuit has been verified using SPICE simulations for 0. 18?m CMOS technology with the supply voltages of ±0. 5V. From the simulation results, it has been observed that the proposed circuit has low p...
Due to their low number of biased components, algorithmic A/D converters are often used in low power implementations. This paper describes an algorithm developed at the Institute of Microtechnology (IMT) which allows extending performances of cyclic RSD converters, without greatly impairing its benefits (reduced silicon area, low consumption). To achieve a Total Harmonic Distortion + Noise (THD...
The most popular and best modulation method used among Pulse Width Modulation (PWM) technique is Space Vector Modulation (SVM) method. SVM generates low Total Harmonic Distortion (THD) and it is well suitable for motor control. Harmonics is one of the major power quality issues occurring in most of the application. SVM holds the major advantage that only one switch is turned on at a time. The p...
The common mode voltage (CMV) causes many issues and negatively affects the performance of power system in a hybrid electric vehicle HEV. Therefore, this paper suggests simple method for mitigating CMV two level three phase source inverter VSI with RL load. Hence, technique chosen purpose is based on model predictive control. Otherwise, when compared to standard method, can successfully mitigat...
Harmonic generation in power system networks presents significant issues that arise utilities. This paper describes a machine learning technique was used to conduct research study on the harmonic analysis of railway stations. The an investigation time series whose values represented total distortion (THD) for electric current. based information collected at station. In electrified substation, m...
An adaptive fuzzy control system with supervisory controller is proposed to improve dynamic performance of three-phase active power filter APF . The proposed adaptive fuzzy controller for APF does not build an accuratemathematical model but approximates the nonlinear characteristics of APF using fuzzy approximation. The adaptive law based on the Lyapunov analysis can adaptively adjust the fuzzy...
An active current injection network for a three-phase diode rectifier is proposed. Current injection is done by using two networks: injection network and injection device. The injection network composed by a half-bridge inverter operating at high frequency and injection device is composed by three bi directional switches operating at low frequency. It also uses one inductor in order to get the ...
This paper presents different kinds of grid-tied cascade H-bridge inverter and has a look to predictive current control technique. Finally the simulation result will show a Model predictive current control of a five-level cascaded H-bridge (CHB) inverter indifferent sampling times by using MATLAB Simulink software. And this Model Predictive current controller (MPC) for the five-level CHB invert...
This paper presents a novel three-phase power factor corrector (PFC) circuit which uses two power switches working in zero-voltage-switching (ZVS) condition. The two switches along with a high-frequency inductor constitute a high-frequency current source which is responsible for the energy transfer in the circuit. The input current is partly continuous and partly discontinuous. The total harmon...
