Project 1

Design a DC power supply using PFC circuit for general purpose applications with 350V dc output and load in the range of 0-7A. The supply should meet the harmonic standard limits for input power quality such that current THD limits are satisfied with input power factor >0.97 value. The input side is connected to single…

Part A: The three-phase diode rectifier is supplying approximately 2.2 kW load with VLL=208V at 60 Hz, Ls=1 mH and Cd=1100 μF, where Cd is the DC side capacitor. Design the circuit in one of the simulation platforms (MATLAB or Ltspice/Simetrix) and obtain the circuit waveforms. Based on their simulation studies…

The project is based on the speed control of DC Motor by using PID controller. Initially the simulink model of DC motor is build and then it is converted to subsytem model named as DC motor. The DC motor subsytem is then connected to PID controller to maintain the desired speed as it is. We adjust the gain values Kp,Ki,Kd…
