How do you build a 5.0V regulated power supply?

Click For Summary
SUMMARY

The discussion centers on building a 5.0V regulated power supply without using standard voltage regulators. The participant expresses uncertainty about how to initiate the project, indicating they have an AC electronics course as a foundation. Key suggestions include consulting textbooks and resources like Wikipedia for foundational knowledge on power supply design. Participants emphasize the importance of understanding different topologies and the potential use of AC mains power (120/240Vrms) in the design process.

PREREQUISITES
  • Basic knowledge of AC electronics
  • Understanding of power supply topologies
  • Familiarity with circuit design principles
  • Ability to read and interpret electronic schematics
NEXT STEPS
  • Research various power supply topologies, such as linear and switching designs
  • Study the principles of rectification and filtering for AC to DC conversion
  • Explore resources on designing power supplies without voltage regulators
  • Review safety protocols for working with AC mains power (120/240Vrms)
USEFUL FOR

Electronics students, hobbyists, and engineers interested in designing custom power supplies, particularly those looking to deepen their understanding of AC power applications and circuit design.

i am stuck. i have no idea how to start on this project. I have to build a power supply that produces 5.0V regulated. i can't use regulators so i have to build it but i have no idea how to get started. i have an ac course to start with. i would appreciate any ideas, insights or designs you might have.

What do you mean that you "have an ac course to start with"? Does that mean that you have taken an AC electronics course in school, or does that mean that you need to design and build your power supply to run off of the AC mains 120/240Vrms power?

What topologies are you considering for your design? When you "have no idea how to start on this project", a good starting point would be your textbooks, or wikipedia.org:
