This document summarizes the key components of a power supply system. It discusses that power can come from AC or DC sources like electric poles or batteries. A power supply system takes the 220V AC supply and modifies it using components like a step down transformer, diodes, and a voltage regulator to output the 3-24V DC needed to power circuits and motors. It also describes the basic functions of diodes and how bridge rectifiers are used to convert AC to DC for use in power supply systems.
2. Power source
An Alternating current(AC) and a Direct current(DC).
AC source:- Electric pole
DC source:- battery
3. Power Supply System
Suitable power supply is needed to run the motors and
associated circuitry
Typical power requirement ranges from 3V to 24V DC
and if we want to use more power than increase the
current of transformer.
220V AC supply must be modified to suit the needs of
our machine
Batteries can also be used to run robots
8. Bridge Rectifier
An electrical device that convert alternating current to
direct current
Types of rectifier
1. Half wave rectifier
2. Full wave rectifier
9. Machine
Machine is anything that reduce human effort.
Types of machine:-
1. static machine
2. rotating machine
