Switching power supply for various applications. For example, it can be used as AC voltage conversion to
And the various trends cited as dimming voltage or voltage that these resources depending on their application to groups
Some of the uses of these resources:
The difference between switching and transformer
1-converting AC voltage to the voltage of different flows
2. Use as a battery charger at home
3-used in electronic circuits and …..
4. In Caption display-driver for led-
Switch mode power transformers are called so due to their switching action needed to sustain transformer operation.
Switch mode power transformers are used in electronic applications, typically within a switch mode power supply.
Switch mode power transformers may have several secondary windings. A switch mode power supply is usually
operated from a D.C. source like battery to convert the input D.C. to other output D.C. sources.
In the switch mode power transformer, you can control the amount of power delivered to the load circuit of the transformer
by controlling the amount of “on time” and “off time” of the switches. Switch mode power transformer features low wastage,
high output power, low temperature rise and wide range of working frequency.
2. The second objection is the high amount of trans
3-weight ratio to the switching power supply transformer
4-warming too trans-even in no-load mode
5-Ripple High Voltage
6-trans casualties is very large relative to the switching power supply
9. The high price of these types of resources
Benefits of Switching
1-small as compared with the trans
2. good stability against power fluctuations
3. Low output ripple
4. Add additional output simply by adding a transformer winding it in a little bit harder
5-lightweight compared to the trans
6 low-loss switching power supplies
7. The high efficiency switching power supplies (87 percent more)
8-needed high-frequency switching power supply filter capacitor working small (about several tens of kHz)
As a result, because of the frequency of the output capacitor is small compared to the trans
9. The low price of this type of resource
Of course, switching power supplies also have their own disadvantages which may be the flaw in noise
Sources further said that this disadvantage can be seen switching cheap and poor quality
