This paper presents PIC microcontroller based PWM inverter controlled four switch three phase inverter (FSTPI) fed Induction Motor drive. The advantage of this inverter that uses of 4 switches instead of conventional 6 switches is lesser switching losses, lower electromagnetic interference (EMI), less complexity of control algorithms and reduced interface(More)
Patients recovering in critical care units are continuously monitored for their hemodynamic states and accordingly given proper medication. The widely monitored hemodynamic variable is the Mean Arterial Pressure (MAP), which is regulated by infusion of vasoactive drugs like Sodium Nitroprusside (SNP). Presently, physicians check the patients’ MAP at regular(More)
A Simulation and experimental implementation of Four Switch Three phase inverter (FSTPI) fed Induction Motor drive is presented in this paper. In this proposed approach the simulation of the system is carried out using MATLAB/Simulink and experimental work is carried out using Spartan-3 processor and Xilinx software. In the experimental work, Xilinx(More)
The variable-speed wind turbines are gaining more prominence due to their ability to generate power for a wide range of wind speeds. This class of turbines requires a fraction of the power be drawn from the grid in order to deliver the promised power when there is a deficiency in wind speed. For this purpose, a Doubly-Fed Induction Generator (DFIG) with a(More)
This paper aims at the study, analysis and simulation of full order or fifth order dynamic equations of asynchronous generator in Matlab-Simulink environment. The asynchronous generator considered here is the squirrel cage induction generator (SCIG). Various SCIG parameters like rotor speed, electromagnetic torque, active power and reactive power under free(More)
