MechatronixOne is a manufacturer of an Industrial and toy robots. They are In the planningSTage to develop a prototype Al robot for Industry that will be supplied by a 12V dc with IzM = 20mA.This Al robot as they envision has a capability to understand little English command. Their problem ishow to design an RC filtered power supply that can be used in their prototype Al robot which has aload range of 2502 to 1.25kQ and since this is just a prototype it must be wired to the 240V 60 Hzpeak ac supply in their laboratory. They ask the VoltageMaker Company to ship them 20 pcs of 12Vdc power supply and it must be included in the data shett the load current In rms and peak, thePIV, the power range absorbed by the load, the ratio of the transformer, and the secondary rmsvoltage of the power supply. The power supply must be in a bridge type. Considering that you area member of that team, what is your design?

FACTS: AC-DC converters take the AC power from wall outlets and convert it to unregulated DC. These power supplies include transformers that change the voltage of the AC that comes through wall outlets, rectifiers to save it from AC to DC and a filter that removes noise from the peaks and troths of the AC power waves.The DC-to-AC Converters are used to charge the batteries in the vehicles. These circuits are mainly used for driving low-power AC motors and are used in a solar power system. The DC to AC converters can be used in dc transmission lines for transmitting power to loads. QUESTION: What do you think is the main reason why we have AC power in our outlets instead of DC power? Explain your answer.
QUESTION 3 is dc -Lac 0 f(t) = Ide T If ripple-free load current in steady-state is assumed, the input current is waveform of the single-phase full-wave rectifier may then be depicted as shown in the figure above for an ideal input transformer. With the assumption that the supply is ideal and perfectly smooth and ripple free load current, which implies an infinitely large load inductance, it is quite straightforward to obtain an analytical expression for the input current harmonics.

1) A dc-dc buck converter has a 48 V input. This converter is connected to a dc motor that spins at 2000 RPM given 24 V at its terminals, 1000 RPM for 12 V, and follows a linear speed relation at other voltages. The motor is characterized by a voltage source in series with an inductance and resistance. The resistance is 0.5 2. The inductance is 10 mH. The converter switches at 20 kHz. At 2000 RPM with no mechanical load, the motor draws 0.5 A. a) What is the no-load motor speed at 20% duty ratio?
