1) simulink model   voltage is given as 800V ie given in parameters in step block the step time is given as 0.1   blocks inside the V/HZ control subsystem in the asynchronous machine parameters, the rotor type is changed into squirrel cage as advised in the parameters   output waveform      …

assuming parameters *Vin = 100 V *Vout = 200 V *L = 200uH  *C = 400uF *R= 10 Ohms *RL = 10 mOhms *RC = 2 mOh   output    

simulink model is done  SOC battery at 208secs    given parameters are total battery current = -24.71 battery resistance = 2  max battery current = 0.896 time  =120 secs jolues heat = (I)^2*RT (0.896)^2*2*120 =192.67 entropic heat = 2*average power =2*3.4 =6.9mv/k max heat generated = 192.67+6.8…

1) given parameters vehicle energy = 150Kw rated motor voltage = 120V cell nominal capacity = 3500mAh or 3.5Ah cell nominal voltage = 3.6V before designing the battery pack , we should find the no of cells in series and parallel no of cells in series = rated motor voltage/nominal cell voltage = 120/3.6 =33.33 no of cells…

part A 1) below screenshot indicates the weight of various aircrafts here the MTOW stands for maximum takeoff weight (this is the maximum weight at which the pilot of the aircraft is allowed to attempt to take off) MLW stands for maximum landing weight which is the maximum weight at which the aircraft is permitted to land…

1) formula for calculating the energy required for braking E = 1/2*m*(vi-vf)^2 here m=mass,vi=initial speed,vf=final speed here i have created my own drive cycle and calculated the braking energy using the formula ,the calculated braking eneergy are in KW   2) below screenshot indicates the speed torque characteristic…

1 A) symbol of bipolar junction transistor BJT A bipolar junction transistor is a three-terminal semiconductor device which consist of base ,collector and emitter terminals H bridge An H-bridge is a simple circuit that lets you control a DC motor to go backward or forward   speed contol of a dc motor using BJT…

1) mapped model engine is classified into two :ci mapped(diesel)and si mapped(petrol) model uses a set of steady state lookup tables to characterize engine performance.it can be used when one has engine data .  tables provides overall engine characteristics i.e fuel flow rate,engine out exhaust emmisions.it can be…

1) the converters used in power electronics are *AC-DC converters(controlled rectifier) *AC-AC converters(AC voltgae controller) *DC-DC converters(DC choppers) *DC-AC converters(inverters) in plug in hybrid vehicle AC to DC converters are used to convert the AC supply at the charging station to DC current because battery…

1) in the above screenshot the vehicle model is selected as EV default in and cargo mass is added as 500kg,the battery used is lead acid with 25 modules .weight of the battery pack is 275kg and the total mass of vehicle is 1508kg here ftp drive cycle is selected and the distance of 1ftp cycle is obtained as 17.77km.below…

the parameters which are required for describing the dc motor such as moment of inertia(J),motor viscous friction constant(B),motor torque(kt),etc has been defined in the m script to find the kp and kd values as usual the place command is used and jacobian matrices are used to define the matrices of A,B.   simulink…
