Week 4 Session 5

Explain the various applications of power converters in on Eletric vehicle, for example what type of converter will you use for horn which requires DC and less than 10v. Likewise comp up with different application.  DC-DC converter DC-AC converter AC-DC converter DC-DC converter DC-DC converter is electronic circuit…

Create a MATLAB model of electric car which uses a battery and a DC motor. Choose suitable blocks from Powertrain block set. Prepare a report about your model including following: Objectives:         1. System level configurations        2. Model parameters      …

1. Search and list out the total weight of various types of aircrafts   Weight is a major factor in airplane construction and operation, and it demands respect from all pilots and particular diligence by all maintenance personnel. Excessive weight reduces the efficiency of an aircraft and the available safety margin…

1.For a defined driving cycle, calculate the energy required for braking.    The driving cycle taken into consideration is the UDDS cycle which stands for Urban Dynamometer Driving Schedule. Although the data is taken for a total driving time for 1370s, for simplicity sake on 150s of driving time is considered.…

1.A. Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’.  B. Comment on the armature current shoot-up from the scope results.   Working     In the above circuit, the input voltage is generated from the pulse generator where the amount of supply and duty…

1.Which types of power converter circuits are employed in electric and hybrid electric vehicle?   A power converter is an electrical circuit that changes the electric energy from one form into the desired form optimized for the specific load. A converter may do one or more functions and give an output that…

1.What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type? Mapped Engine :  Mapped engine is the default settings in powertrain blockset.It is used to measure the performance parameter of the vehicle by using standard lookup table which are preferd to the…

  For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle? Conclude your observations. # Drive cycle 2 # Drive cycle 3 2.In the above case, try changing the battery capacity and repeat the simulation. #Drive cycle 2 Energy storage with…

Obtain the transfer function of a mass spring damper system and use it in the model. Add a PID controller to adjust the force on mass so that its position follows a reference signal. Take m = 3.6; %kg k = 400; %N/m c = 100; %Ns/m.   Model: the transfer function for the mass spring damper system is …

Project : In a laboratory experiment, data of voltage and current has been recorded and the same is attached in an excel file ( Click on this link VI.xlsx ). Read the excel file in the Matlab program and perform the interpolation in the range of -17.3:0.1:0.9. Generate the interactive plot for the interpolated…
