• Converts one voltage to another.
• Generates electrical power from mechanical energy.

The design process of a power supply typically starts from the:

• Input and proceeds to the output.
• Internal components and then input/output.
• Output and works backward to the input.
• Primary voltage source.

A rectifier is an electronic circuit used to convert:
