Elektor Special: Power Supplies and Batteries

Description

Whatever the methods or even then financial means you have to make your circuits work, the power supply should rank high if not Number One in your considerations. The design block simply called “power supply” is hugely underrated both in electronics creation and repair. Yet, the “PSU” has enormous diversity and comes in wildly differing guises like AC/DC, generator, battery (rechargeable or not), PV panel, benchtop, linear or switch-mode, to mention but a few. The output ranges are also staggering like nano-amps to kiloamps and the same for voltages.

This special covers the features and design aspects of power supplies.

Contents

Basics

  • Battery Management
    What to be aware of when using (Lithium) batteries.
  • Fixed-Voltage Power Supply using Linear Regulators
    The best result right after batteries.
  • Light Energy Harvesting
    A small solar panel is used in an energy harvesting project to manage and charge four AAA cells.
  • Mains Powered Adapter Design
    Basic circuits and tips for transformers, rectification, filtering and stabilization.
  • LM317 Soft Start
    The high inrush current pulse should be avoided.
  • Controllable Rectifiers
    Some suggestions to keep the power loss in the linear regulator as low as possible.

Components

  • Worksheet: The LM117 / LM217 / LM317 Voltage Regulators
  • Supercaps
    Low voltage but lots of current… or not?
