REGULATED POWER SUPPLY 1. AIM Design question: Design and realise a regulated power supply with following minimum specifications. Load voltage-adjustable from 1.25 V-18 V. Maximum load current -0.75 A 2. PRINCIPLE Summarise the principle of a full wave bridge rectifier, three terminal regulators with all necessary design formulae. 3. CIRCUIT DIAGRAM Provide the complete circuit diagram (all components and their values) labelled here. 4. DESIGN 4.1 Design of adjustable 3-terminal regulators Design data, Assumptions used Calculation of R1, R2, choose appropriate E12 values. Required VDC unregulated 4.2 Design of FWBR Calculation of Vrpp for available filter capacitor and required load current Minimum turns ratio and power specifications of transformer Calculation and selection of fuxe Any assumptions used 5. RESULTS Table 1: Load Regulation measured at the output of the regulator VL (no load voltage) (V) I.(load current) (A) R (load resistance) (52) 108 81 54 27 V (loaded voltage) (V) %Regulation- V V 100% 6. CONCLUSION Answer this section as follows: Assume statement under aim as a question, Voltage across the RL at different load currents, Percentage load regulation Any possible improvement.
