www.thetoppersway.com Seminar On Regulated Power Supply Submitted To: www.thetoppersway.com Submitted By: www.thetoppersway.com CONTENT Introduction Why power supply Detailed Design Component Names and Specification Circuit Diagram & graph Power supply safety Future scope of the project References INTRODUCTION The LM 317 series is adjustable to three terminal positive voltage regulators. The different grades of regulators in the series are available with output voltage of 1.2 to 57 volts and output current from 0.1 to 1.5 ampere. Power supplies provide the necessary power, voltage and current requirements for electronic devices. They usually change ac to dc voltage. For example, 120 volts ac is changed to 13.8 volts dc. DETAILED DESIGN CIRCUIT DIAGRAM & GRAPH • • Grounding is important. Connection integrity is important. – Somewhere neutral and ground are connected together. Bleeder resistors across the filter capacitors “bleed off” charge when supply is turned off. FUTURE SCOPE OF THE PROJECT LM 317 has many future prospects. By using LM 317 we can easily overcome the noise effect of the circuit and by changing the load resistance and voltage the noise effect can further be diminished. So that we get an error free output voltage. In other words LM 317 is highly proficient in making a circuit error free and flawless.
