shunt active power filter projects
Shunt Active Power Filter(APF) is a device that is connected in parallel to group of loads. APF cancels the reactive and harmonic currents drawn by the load so as to make supply current sinusoidal. Active Power Filter play a vital role in present day liberalized energy market.
shunt Active Power Filter are explored for executing different power conditioning function simultaneously along with harmonic elimination due to increase in nonlinear and unbalanced load, at the point of common coupling.
shunt active power filter The aim of present dissertation is to study different control strategies for Active Power Filter. More importantly to study instantaneous power theory based Shunt Active Power Filter which is predominantly used in present scenario.
shunt active power filter is investigated through Matlab/Simulink simulation under different load conditions. Simulation results are discussed in depth. Then the design issues of Active Power Filter for different load conditions are also discussed.
Electric Vehicle Drive with MATLAB/Simulink
Electric vehicle drive The paper presents the simulation of a basic electric vehicle motor-drive system that is used to investigate power flow during both motoring and regeneration. Electric vehicle drive The simulation assumes a DC permanent magnet motor, an ideal motor controller combined with a proportional-integral controller, and the electric vehicle battery.
Electric vehicle drive The model can be used to evaluate the electric drive’s energy flow and efficiency for specific speed and torque load conditions. Some of the key system parameters were specified and others were modeled as ideal. Electric vehicle drive A stable MATLAB/Simulink model was developed and validated. It was then used to determine the system performance and energy flow over a given set of motoring and regeneration speed/torque conditions.
Electric vehicle drive The model could be used to augment instruction in energy conversion or vehicle systems courses.
Maximum power point tracking This paper proposes a maximum power point tracking scheme using neural networks for a grid connected photovoltaic system. The system is composed of a photovoltaic array, a boost converter, a three phase inverter and grid. The neural network proposed can predict the required terminal voltage of the array in order to obtain maximum power.
Maximum power point tracking The duty cycle is calculated and the boost converter switches are controlled. Hysteresis current technique is applied on the three phase inverter so that the output voltage of the converter remains constant at any required set point. The complete system is simulated using MATLAB/SIMULINK software under sudden weather conditions changes. Results show accurate and fast response of the converter and inverter control and which leads to fast maximum power point tracking.
BLDC Drives Fuzzy Logic Controller
BLDC Drives There are basically two ways to achieve high power density and high efficiency drives. The first technique is to employ high-speed motors, so that motor volume and weight are greatly reduced for the same rated output power. Most adjustable speed drive systems employ a single three-phase induction motor.
BLDC Drives With such a drive system, the drive has to be shut down if any phase fails. In order to improve reliability of drive systems, six-phase induction motors fed by double current source inverters have been introduced. Compared to induction motors, permanent magnet (PM) motors have higher efficiency due to the elimination of magnetizing current and copper loss in the rotor. It has become possible because of their superior performance in terms of high efficiency, fast response, weight, precise and accurate control, high reliability, maintenance free operation, brushless construction and reduced size.
BLDC Drives This project presents a current blocking strategy of brushless DC (BLDC) motor drive to prolong the capacity voltage of batteries per charge in electric vehicle applications. The BLDC motor employs a fuzzy controller for torque hysteresis control (THC) that can offer a robust control and quick torque dynamic performance. The proposed concept is verified by using Matlab/Simulink software and the corresponding results are presented.
Single Phase to Three Phase Converter List
Three Phase Converter projects An economic single-phase to three- phase converter which provides variable output voltage and soft starting capability by using four high frequency switches (IGBT, MOSFET), four diodes, and a triac. This converter can run a three-phase Induction motor which is much more able compared to a single phase motor.
Three Phase Converter projects In order to have a balanced output voltage in all modes of operation (start-up, speed control, and steady state) two closed loop controllers has been utilized: one for dc link voltage and the other one for inverter output. The proposed scheme with variable output voltage and fixed frequency provides a limited-range speed control of the induction motor.
Three Phase Converter projects As a result, the new single-phase to three-phase converter brings the controllable output voltage as in a six-switches standard three- phase inverter. The front-end rectifier has the capacity of active input current shaping. Analysis and simulation results are presented in the result section to display these new features.
