Week-11 Challenge: Braking Q1. For a defined driving cycle, calculate the energy required for braking. Calculating the energy required for braking of UDDS Drive Cycle- Braking: Braking is a condition to slow down or stops a moving vehicle as required. There are several techniques to apply brakes, which can be mechanical…

Description of DC motor using BJT H-bridge:   The Bipolar Junction Transistor (BJT) when used for power switching applications, operates as an IGBT. When it is conducting (BJT operating in the saturated region), a forward voltage Vf is developed between collector and emitter (in the range of 1 V). Therefore, the IGBT block…

They are listed and elaborated upon below:   AC to DC converter This type of converter takes an AC…

1.What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?  Ans:powertrain blockset provides two types of combustion engine models:mapped and dynamic. Mapped engine: 1.Mapped engines represent macro engine behaviour as a set of lookup tables(brake torque,fuel…

  A model written in the widely used MATLAB/Simulink software environment. This is a tool stands for 'Advanced Vehicle Simulator' which is used to model different types of vehicles such as some IC engine based and electric vehicles, Hybrid vehicles and Fuel cell-based vehicles, this tool is very useful in case…

a)Start up behaviour of induction motor represented in stationary d-q frame where w=0. In that case rotor speed reaches approx. 377 rad/s on appying load speed decreases by some value and after removal of load it again increases. In stationary reference frame, Vds and Vqs are having constant frequency of 60 Hz. THis does…

MODEL:-               The major principle of MPPT is to extract the maximum available power from PV module by making them operate at the most efficient voltage (maximum power point). That is to say: MPPT checks output of PV module, compares it to battery voltage then fixes what is…

The single-ended primary-inductor converter (SEPIC)                                   The SEPIC converter allows a range of dc voltage to beadjusted to maintain a constant voltage output. For the SEPIC, when the pulse is high/the…
