POWER SUPPLY

There are many types of power supply. Most are designed to convert high voltage AC mains electricity to a suitable low voltage supply for electronics circuits and other devices. A power supply can by broken down into a series of blocks, each of which performs a particular function.
For example a 5V regulated supply:

• Transformer - steps down high voltage AC mains to low voltage AC.
  
• Rectifier - converts AC to DC, but the DC output is varying.
  
• Smoothing - smooths the DC from varying greatly to a small ripple.
  
• Regulator - eliminates ripple by setting DC output to a fixed voltage.
