simulation and calculation part

1.0 The Problem A design company (FOCUS Sdn. Bhd.-CEO: Ahamed Khan) is offering a contract for UCSI EM104 -Electrical Power students to design the following circuits for Telecom applications: 1. A Full wave Rectifier circuit [2 Diode, Center tapped Transformer circuit]. 2. Full wave Bridge Rectifier circuit. The specifications of both the converters are as follows: i) Input voltage is single phase 240 V AC, 50 Hz. ii) The average output voltage can be varied from 6 V to 30 V and its ripple must be less than 1 %. iii) The load is 300 iv) It has to be as light as possible. v) Both the transformer rating and the diode Peak Inverse Voltage [PIV] rating must meet your design considerations. 2.0 The Design You are free to choose any topology you like as long as requirements (i), (ii), (iii), (iv) and (v) are satisfied fully. However, since you are competing for the contract, the design will be graded according to its merit. Your merit is based on the following factors: i) Compliance to the specifications. ii) Equipment weight. iii) Steps involved in the design of Full wave rectifier circuit and Bridge Full Wave Rectifier circuit. iv) Setting the transformer ratio and capacitance value. v) Calculating the ripple percentage without capacitive filter. vi) Calculating the capacitor value. vii) Calculating ripple percentage with smoothing capacitor and performance parameters. xi) Results and Discussion 3.0 Design Verification All designs have to be verified using Multisim / Matlab simulation / other computer simulation softwares. You are free to simulate and choose whatever simulation parameters, but grades will be based on how good you make your judgments on simulation techniques. Specify the value of each component. Assume ideal components .Use an Ideal diode. Determine the output ripple voltage and the following performance parameters of both Full wave and Bridge rectifier circuits you. Compare your simulation results with the analytic results. i) The efficiency (). ii) The Form Factor (FF) iii) The Ripple Factor (FF) iv) The Peak Inverse Voltage (PIV) v) The Transformer Utilization Factor (TUF) Check the text book by the author Muhammad Rashid Power Electronics devices and applications for formula. vi) In Power electronic converters one of the major issue is the harmonic content in the output. In your design a capacitor is used. Identify two more filters which can also be used. For better voltage and current smoothening which one is the best filter? Justify your answer. 4.0 Report. The format of the report is as follows: i) Objective ii) Converter theory iii) Design philosophy iv) Hand calculation related to section 2.0 and 3.0. v) MULTISIM / Matlab simulation / other computer simulation softwares vi) Discussion vii) Proposal for future improvements and conclusion.
