SMPS
SMPS ( Switched Mode
Power Supply ) is a device which gives electric power to other parts of
computer. SMPS is different from other power supply because it gives power
according to the need of computer. Like other power supply devices SMPS loads
the electricity first and then changes into voltage and current. After this,
current reaches to the main power supply. SMPS changes D.C power to D.C. and
D.C. power to A.C. This has different types of regulators which are useful in
LPS ( Linear Power Supply ) because it has ability to handle the Voltage. It
gives power to every part of computer according to their need especially to
transistor and diode. The regulator of SMPS works on different power supply.
That’s why SMPS is most important part of computer. CLICK HERE TO KNOW What is Mother Board Explains its All Parts and Function ...

Type of SMPS :
1. D.C
to D.C Converter
2. Forward
Converter
3. Flyback
Converter
4. Self
– Oscillating Flyback Converter
D.C. Converter :
The first power comes to
SMPS is in the form of AC, which filters to DC. Then it changes the power with
the speed of 15 KHZ to 50 KHZ. With that it gives power to step down transform
( The size of step down transformer may be 50 Hz unit ), after this the power
supply goes to the output and one sample of this output sends to switch to
control the output voltage.
The power provides to
D.C. that needs to break at the frequency of 15 to 50 KHz. To do this any
active device like BJT, Power MOSFET, SCR and a transformer needs to use. The
lowest limit of it is almost 5 KHz and the maximum is 50 KHz. After this it filters
all the changed electric rays.
The control elements of
SMPS are made of transistor, inductor or diode. As we switches on the electric
power combines to inductor and changes into magnetic field. Then SMPS sends
this power forward and according to the level of Voltage. CLICK HERE TO KNOW What is ROM Read Only Memory Its Type and Uses ...

| Advantages Disadvantages of SMPS |
Benefits of SMPS :
· The
biggest benefit of SMPS is that it can fulfill the requirement of power at low
power as well.
· With
that it is small and light, while transformers are big and heavy.
· It
releases low heat and that depends on its ability.
Losses of SMPS :
· This
is hard to understand the working of SMPS.
· Its
high amplitude and high frequency is also a drawback because it decreases the
level of filtration.
· SMPS
is a cause of harmonic distortion.
SMPS situates at the
upper outside of CPU, it has sockets at its one side while it has a plug at the
other side to connect with main power supply. All the wires of SMPS join the
different parts of mother board and supply power to them.
