Project 1

Problem statements: Part A: 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…

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…

Design of boost converter, and calculating the loss of different components including power switching device and deriving efficiency of boost converter. This is applicable in power supply industry, electric vehicles etc where DC-DC converter is required to boost the voltage from DC source. All the aspects of this project…

1) Designing an interleaving DC/DC converter for a data centre application with the following specifications :- - Input voltage :- 45-60 V - Output voltage :- 3 V - Output current :- 100 A - Efficiency > 85%   - First we need to calculate the required parameter values to design the above converter and the calculations…

- Choosing any three topologies from the above given and developing them in the simulink :- 1) Buck CCM :- Given data :- Input voltage = 40-50 V Output voltage = 30 V Power =500 W - The schematic diagram for the above converter is shown below :-   - To design the above buck converter we need to design inductor, capacitor…

Summary :- 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…
