2. Index…
• What is Power supply?
• Need for Power supply
• Elements of Power supply
• Filters
• Voltage Regulators
• A basic Power supply

3. Why we go for power
supply studies?
All electronic circuits need
smooth DC power supply in order
to function correctly.
The DC power supplied either
from battery or power pack
units

4. Power Supply
• Introduction:
• It is an electronic device that supplies electric energy. The
primary function of power supply is to convert one form of
electrical energy to another that is AC into DC.
• Modern personal computers universally use switched-mode
power supplies (SMPS)
• A power supply is a component that supplies power to at
least one electric load. Typically, it converts one type
of electrical power to another, but it may also convert a
different form of energy – such as solar, mechanical, or
chemical - into electrical energy. A power supply provides
components with electric power.

5. What is power supply?
• A device, which converts, regulates, and
transmits the required power to the circuit to be
operated.
• The power supply can be defined as it is an
electrical device used to give electrical supply to
electrical loads.

6. Function…
 The primary function of a power supply is to convert
electric current from a source to the correct voltage.
 The desktop computer power supply changes alternating
current from a wall socket of mains electricity to low-
voltage direct current to operate the processor and
peripheral devices.
 It also controls over-heating through controlling voltage,
which may modify manually or automatically based on the
power supply. The PSU or power supply unit is also called as
a power converter or a power pack.

7. Keep in mind
• In a computer, the internal components
like cases, motherboards, & power supplies
all available in different configurations,
sizes which are known as form factor. All
these three components must be well-
matched to work appropriately together.
