1.  Which types of power converter circuits are employed in electric and hybrid electric vehicle?    Ans: - Power Converters in EV and HEV Electric Vehicles: An electric vehicle (EV) is a vehicle that uses one or more electric motors or traction motors for propulsion. An electric vehicle may…

1.   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. Ans:- Now open the ADVISOR Tool, set the load file to 'EV_defaults_in' The above table before giving the mass of 500kg. The below table after…

1. A. Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’. Ans: - Model Blocks Used Switches Diode The diode is a semiconductor device that is controlled by its own voltage Vak and current Iak. When a diode is forward biased (Vak > 0), it starts to conduct with a small forward…

1. For a defined driving cycle, calculate the energy required for braking. Ans: - Braking: The function of the braking system is to retard the speed of the moving vehicle or bring it to rest in the shortest possible distance whenever required. The vehicle can be held on an inclined surface against the pull of gravity by…

Explain the various applications of Power converters in an Electric vehicle. For Example what type of converter will you use for Horn which requires DC and less than 10V. Likewise come up with different applications Ans: - 1. DC-DC Converter DC-DC converters in an electric vehicle may be classified into unidirectional…

Search and list out the total weight of various types of aircrafts.  Ans: - MTOW = Maximum take-off weight, MLW = Maximum landing weight Type MTOW [kg] MLW [tonnes] Antonov An-225 6,40,000 591.7 Airbus A380-800[2][3][4] 5,75,000 394 Boeing 747-8F 4,47,700 346.091 Boeing 747-8 4,43,613 306.175 Boeing 747-400ER…

1. What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?  Ans: - Mapped Model Model uses a set of steady-state lookup tables to characterize engine performance. Mapped models are used when the behavior of a particular model is not of our interest and…
