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 manufacturers device performance data books to select appropriate devices (Zener, IC regulator, op. amp.) for your design.
