Detailed Question: Design a regulated DC power supply for the following specifications and verify your design using SPICE.

Specifications:

Desired D.C. Output: 10 V

Load Variation: 0.3 - 10 kW

Ripple Factor: Less than 0.1% for 2 kW load

Load Regulation: Better than 3 mV for a 1 mA change in load current

Line Regulation: Better than 3 mV for a 1V change in line voltage

Design Restrictions: Capacitor values in your design should not exceed 50 mF. In case if you need a bigger capacitor use an op. amp. based capacitor simulator.

Output Stage: First as the output stage use a Zener shunt regulator and then replace the Zener shunt regulator with an appropriate IC voltage regulator. Do the SPICE simulation of the whole circuit, which has the Zener shunt regulator as the last stage. Do the literature search to gather information on op. amp. capacitor simulator and IC voltage regulators. Also look at manufacturer's device performance data books to select appropriate devices (Zener, IC regulator, op. amp.) for your design.

Deliverables: A formal written report which includes your hand calculations and SPICE printouts of signals at various nodes of your design.
