Chapter 17, Problem 16RP

Consider the circuit diagram below. If four identical capacitors, each with a capacitance of 0.07 F, are used to smooth the output, what will the ripple voltage VR be? The diode forward bias voltage, VF, is found to be 0.5 V.  Note that the amplitude of v(t) is given in VRMS.

a) Find the complex power absorbed by the -j3 ohm  capacitor to 3 decimal points.b) Find the complex power absorbed by the 4 ohm resistor to 3 decimal pointsc) Find the complex power absorbed by the j5 ohm inductor to 3 decimal points.

I am looking for schematic ideas or recommendations for designing the required step-down system. Since the input is a 600V DC supply, a DC-DC converter may be necessary, as transformers are typically used for AC voltage. Key considerations would include: Voltage regulation: Ensuring a stable and consistent 120V DC output.Component selection: Choosing appropriate DC-DC converter modules, capacitors for filtering, and protective components such as fuses or circuit breakers.Lighting system: Recommendations on energy-efficient lighting options like LEDs, which work well with DC power and offer durability for railway applications.Thermal management: Addressing heat dissipation within the converter and lighting circuit.Safety and standards: Complying with safety regulations for electrical systems in railways. I would greatly appreciate detailed insights into the design process, including key circuit components and configurations, as well as any schematic diagrams or references.
