Performance Level Criteria
Fail
(< 40%) Report contains very little relevant information and little or no conclusion. No simulation results or calculations are given.
3rd Class / PASS
(40% - 49%) Report contains the bare minimum information. Little work done in researching around the subject. A basic schematic diagram and description have been produced, but with errors.
Lower 2nd Class / PASS
(50% - 59%) Report contains basic information. Report shows that research has been undertaken in the subject area. A schematic diagram and description have been produced, but with some errors. No critical evaluation of the design has been included.
Upper 2nd Class / MERIT
(60% - 69%) Report addresses all parts of the assignment, and demonstrates that research has been done in the area and clearly shows its relevance. A schematic diagram and description have been produced. An evaluation of the design has been included.
1st Class / DISTINCTION
(70% +) Report addresses all parts of the assignment, and demonstrates that extensive research has been done in the area. A schematic diagram and calculation have been produced, with comprehensive descriptions. A critical evaluation of the design has been included.

ASSESSMENT- DETAILED REQUIREMENTS
1. Introduction
The aim of this assignment is to design and evaluate a stabilised discrete linear power supply. The power supply needs to be designed according to the specification outlined below and evaluated using a circuit simulator.
2. Specification
A stabilised discrete linear power supply needs to be designed. The power supply can only use discrete components, e.g. transformer, resistors, diodes, transistors, etc. The only exception is Operational Amplifiers (opamps) which may be used. The power supply needs to conform to the following specifications:
• Input Voltage: mains 230V, 50Hz
• Output Voltage: 10V
• Maximum output current: 1A
• Short-circuit protection
• Current limiting
• Low quiescent current.
The power supply needs to be able to cope with input voltage changes as well as with load current changes (Line regulation & Load regulation).
1. Using the circuit simulator, evaluate the performance of your design with respect to:
(i) power consumption (based on quiescent current)
(ii) dropout voltage
(iii) ripple rejection
(iv) load regulation (as %)
(v) line regulation (assume ±10% variation on mains voltage).
2. Compare your results with a simulation of a standard IC linear regulator of your choice (e.g. 7805).
3. If the maximum output current is to be increased to 2A what changes would be needed in your circuit? Recommend, and justify the choice of, any component changes.
3. Report
Your report for this assignment should include,
• schematic diagrams,
• calculations for all component values,
• a description/justification of your component choices,
• the simulation results
• a critical evaluation of your design
英国代写assignment Furthermore, the report should contain an introduction and conclusion. Simulation results should be presented in a readable format.
Note that all work handed in after the submission date and within 5 working days will be capped at 40%. No marks will be awarded if the assignment is submitted after the late submission date unless mitigating circumstances are applied for and accepted.
