Briefly explain what Boost converter is and mention its main applications.
b) With the aid of steady state waveform and switch ON switch OFF equivalent circuit derive the expression of the voltage gain of boost converter in continuous conduction mode.
c) The duty ratio of the boost converter is adjusted to regulate the output voltage at 96 V. The input voltage varies in wide range from 24 V - 72 V. The maximum power output is 240 W. The switching frequency is 50 KHz. Calculate the value of inductor that will ensure continuous current conduction mode.
Answers
a) Boost converter is a switching converter that converts the input voltage to a higher output voltage level. The boost converter output voltage is always greater than the input voltage. Boost converters are also known as step-up converters because the output voltage is higher than the input voltage. Applications: DC power supplies, laptop adapters, mobile chargers, electric vehicles, etc.
b) continuous conduction mode can be derived as follows:
Vo / Vin = 1 / (1 - D)
c) The value of inductor that will ensure continuous current conduction mode is 26.7 μH.
a) The main applications of boost converters include:
Power supplies: Boost converters are commonly used in power supply circuits to step up the voltage from a lower source voltage to a higher level required by the load.Battery charging: Boost converters can be used to charge batteries with a higher voltage than the available source voltage.LED drivers: Boost converters are used in LED lighting applications to provide a higher voltage for driving the LEDs.Renewable energy systems: Boost converters are employed in renewable energy systems such as solar panels and wind turbines to boost the low input voltages to a higher level for power conversion and grid integration.b) In continuous conduction mode, the boost converter operates with a continuous current flowing through the inductor. The steady-state waveform and switch ON-OFF equivalent circuit can be used to derive the expression for the voltage gain of the boost converter.
Let's denote the duty cycle of the switch as 'D' (D = Ton / T, where Ton is the switch ON time and T is the switching period). The voltage gain (Vo / Vin) of the boost converter in continuous conduction mode can be derived as follows:
Vo / Vin = 1 / (1 - D)
c) Given that the input voltage varies from 24 V to 72 V and the maximum output power is 240 W. We know that Power P = V x I, where V is voltage and I is current. Inductor current (I) in the continuous conduction mode is given
asIL = (Vout x D x T)/L Where, T is the switching period
L = (Vin - Vout) x D x T/ (2 x Vout x ILmax) ILmax is the maximum inductor current at the output side.
ILmax = Pmax / Vout
Let's calculate the maximum inductor current:
ILmax = 240 W/ 96 V = 2.5 A
Assuming the duty ratio D to be 0.5, and switching frequency f as 50 kHz, the switching period T is given as:
T = 1/f = 20 μs.
The output voltage is Vout = 96 V and input voltage is 72 V.
Thus, the voltage across the inductor is given as follows:
Vs = Vin - Vout = 72 V - 96 V = -24 V (negative because it is in step-up mode)
Substituting these values in the above equation, we get
L = (72 - 96) x 0.5 x 20 x 10^-6 / (2 x 96 x 2.5) = 2.67 x 10^-5 H = 26.7 μH
The value of inductor that will ensure continuous current conduction mode is 26.7 μH.

a 3-phase motor is 82% efficient and operates at a power factor of 77% lagging. the line voltage is 480 vac and the line current is 15a. what is the apparent, reactive and actual power supplied to the motor and the power produced by the motor, in watts and horsepower? what is the impedance, resistance and reactance of each phase of the motor?
Answers
The apparent power is the product of the voltage and the current, so the apparent power is 480 VAC x 15 A = 7,200 VA. The power factor is 0.77 lagging, so the reactive power is 7,200 x 0.77 = 5,544 VAR. The actual power supplied to the motor is the product of the apparent power and the efficiency, which is 7,200 x 0.82 = 5,824 W.
The power produced by the motor is 5,824 W divided by the efficiency, so the power produced by the motor is 5,824/0.82 = 7,121 W or 9.5 HP.
The impedance, resistance, and reactance of each phase of the motor depending on the type of motor and the design of the windings. Generally, the impedance is determined by the resistance and the reactance, so the impedance of each phase can be calculated using Ohm's law. The resistance and reactance are usually determined experimentally using an ohmmeter or an AC clamp meter.

When walking steadily at 5 km/h with no extra load, A is working at 30% of his VO2 max, and B at 40% of his VO2 max. If each of them has to carry a 30 kg load that requires the consumption of one additional liter of oxygen per minute, which worker will tire more quickly?
Answers
Worker A is more likely to tire more quickly than worker B as per the given scenario.
What is VO2 max?When you exercise as hard as you can, your VO2 max evaluates how much oxygen (often measured in milliliters) you breathe in.
To determine which worker will tire more quickly, we need to calculate their relative workloads while carrying the additional load.
Worker A:
VO2 max = 65 mL/kg/minBody weight = 65 kgVO2 at 30% capacity = 0.3 x 65 mL/kg/min = 19.5 mL/min/kgWith additional 30 kg load, VO2 = 19.5 mL/min/kg + 1000 mL/min / 65 kg = 34.2 mL/min/kgWorker B:
VO2 max = 52 mL/kg/minBody weight = 104 kgVO2 at 40% capacity = 0.4 x 52 mL/kg/min = 20.8 mL/min/kgWith additional 30 kg load, VO2 = 20.8 mL/min/kg + 1000 mL/min / 104 kg = 30.6 mL/min/kgWe can see from the calculations above that worker A will be bearing the additional load while working at a higher percentage of his VO2 max than worker B.
Thus, worker A is more likely than worker B to become fatigued more rapidly.

What is the source term in Algebraic Equations?
In the finite-element method of Analysis, we usually go from differential equations to a set of algebraic equations. Now, it is pertinent to note that each algebraic equation will tend to relate a nodal value with all other nodal values.
The assumed polynomial variation that will exist within each element is usually the basis for which we derive the algebraic equations. Thus, to derive the algebraic equations, we will have to assume a polynomial variation for the parameter values within each element.
The above can be done through interpolation of nodal parameter values in the post-processing stage. This is because the assumed polynomial variation within each element that is used for deriving the algebraic equations is also used for post-processing.
Finally, for each algebraic equation, the source term will tend to contribute to the coefficient that is taken to the right hand side of it and then entered into the corresponding row of the {f} vector.

if the overcurrent protective device is located on a generator outside that supplies a separate building or structure, then the feeder is on the load side of an overcurrent device. in this case, the equipment bonding jumper (load side) with the feeder is sized based on the requirements in section 250.102(c).
Answers
In the scenario where the overcurrent protective device is located on a generator outside that supplies a separate building or structure, and the feeder is on the load side of an overcurrent device, the equipment bonding jumper (load side) with the feeder is indeed sized based on the requirements in Section 250.102(c).
According to the National Electrical Code (NEC) in Section 250.102(c), the equipment bonding jumper is sized based on the rating of the feeder overcurrent protective device. The bonding jumper connects the grounded conductor (neutral) to the equipment grounding conductor, ensuring effective bonding and grounding of the electrical system.
In this case, because the feeder is on the load side of the overcurrent device located on the generator, the bonding jumper's size is determined by the rating of the feeder's overcurrent protective device. This ensures that adequate fault current will flow through the bonding jumper in the event of a fault, allowing the overcurrent device to operate effectively and clear the fault.
It is important to consult the specific requirements of the NEC and any applicable local electrical codes to ensure compliance with the proper sizing and installation of equipment bonding jumpers.

Answers
The correct option is (b) about 10 times higher than in the Milky Way.
Supernovae explosions in a starburst galaxy with a star formation rate 10 times faster than the Milky Way occur at a rate approximately 10 times higher. Supernovae are massive explosions that occur at the end of a star's life cycle. In a starburst galaxy, where stars are forming at a much faster rate than in the Milky Way, the number of supernovae is also expected to be higher.
Studies have shown that the rate of supernovae in a starburst galaxy can be up to 100 times higher than in the Milky Way. This is because there are more massive stars in a starburst galaxy, and massive stars tend to explode more frequently than smaller stars, hence option (b) is correct.

Answers
Answer:
698.3KpaExplanation:
Step one:
given data
V1=0.25m^3
T1=290k
P1=100kPa
V2=0.5m^2
T2=405k
P2=? final pressure
Step two:
The combined gas equation is given as
P1V1/T1=P2V2/T2
Substituting we have
(100*0.25)/290=P2*0.05/405
25/290=0.5P2/405
0.086=0.05P2/405
cross multiply
0.086*405=0.05P2
34.9=0.05P2
