Mathematical modeling of the system: A mathematical model of a dynamic system is defined as a set of equations that represents the dynamics of the system. The dynamics may be obtained by using physical laws governing a particular system.   Step 1: Obtaining differential equations using physical laws   Modeling…

1. Buck ccm: Design parameters:   Circuit design: Zoomed out waveform : Zoomed out : Maximum peak value = 30.65v Minimum peak value = 29.98 v  output ripple = 30.65 - 29.8 = 0.85 v (~3%) Output voltage =~30v Inductor current = ~16.5A Mosfet and Diode current and voltage waveform: 10. buck ccm: The maximum peak…

Circuit diagram:   Input voltage = 60V   Input current = 5A   Output Voltage = 3V   Output Current = 100A from all the above data, we get the Input power is 300W and output Power is also 300W so our efficiency is 100% without considering the ripple in voltage and current, if we consider the ripple also we can get the eifficiency…

 1. For a defined driving cycle, calculate the energy required for braking. To calculate the energy required for braking during a defined driving cycle, we need to know the following parameters: The mass of the vehicle The initial velocity of the vehicle The final velocity of the vehicle The distance covered during the…

Part A: 1. Search and list out the total weight of various types of aircrafts.  Ultralight aircraft: 254 pounds (115 kg) or less. These are small, lightweight aircraft that are used for recreational flying. They are usually powered by a small engine or by gliding, and are capable of speeds up to 65 mph (105 km/h).…

To design a battery pack for a car with a power output of 150 kW and a voltage of 120V, we need to determine the number of cells required. First, we need to convert the power output from kW to W: 150 kW = 150,000 W Next, we need to calculate the current required to produce 150,000 W at 120V: I = P / V = 150,000 / 120 =…
