There are two questions but the one I need answered is the
second one, which uses the first one as reference.
1. Design a zener shunt regulator to provide a regulated voltage of about 10V. You can use a zener diode of type 1N4740 (such as the 1N4740A-ND sold at digikey.com) A voltage supply Vs with a nominal value of 20V 25% is available. The regulator is required to supply a load current of 0 mA to 20 mA. Design...

You need to design a DC power supply that provides an average DC output voltage of 5V to charge your cellphone. The maximum allowed ripple at the output is ±200 mV. Your cellphone can be modeled as a 1 50Ω load. You have to use a bridge rectifier with four diodes. Note: For calculations, consider constant voltage drop model of the diode with V0 = 0.7V. (a) The charger is designed to use in the US, i.e. transformer primary is...

Design a FULL WAVE BRIDGE RECTIFIER circuit that will:
Take 120volts ac, 60 hz, sinusoidal waveform and convert
it to a “regulated “dc value
giving 12 volts +, - 1 volt across a 2000-ohm output
load resistor with no more than 2%
ripple voltage.
You may assume:
a. An ideal power transformer as discussed in class.
b. For hand computations, you must assume a diode given by
Figure 4.8 page 185.
c. A filter capacitor sized per the textbook equation...

For the questions on this page, assume that that an induction motor is rated to deliver 10kW (approximately 13.3HP} when operated at 240VRMS 60Hz. The motor has a lagging power factor of 0.8. The building electrical service only supplies 208VRMs, so the motor can not be connected directly to the electric service. An ideal transformer is used to create...
