There are two types of processors on the market-linear transformer and a power transformer switching. The processor design is different. Sometimes referred to and AC Power Adapter. Linear Transformer used especially in radio, project teams, VCD and so on any processor mode switch can be found on the monitor, TV, fax, etc..

A transformer comprises two or more coils on the same kernel. For power transformers, the material base usually iron. For a radio frequency transformer, the base material is usually ferrite or air. The fundamental property transformer is to change the AC voltage. A transformer can not change the voltage current. A transformer has not reduced yield ac its secondary winding voltage power input to the primary winding. However, a transformer measuring more than half the primary voltage. The plate processor or enamel paint or varnish is to insulate, it becomes next to short-circuit between the winding. I will not go into too much detail on how the work of counting and arithmetic processor as you can read more details from the Transformers books e compared to other components. If too much current passes through a coil or winding up, liquidation is heated and can be opened completely, or the insulation between the turns of wire can break, causing the coil to be partially or completely bypassed.

As a coil, you can check continuity of any primary or secondary. The actual value of DC resistance reading is rather insignificant, but at least you know if a settlement is open. Checking the linear transformation is very simple. Applying voltage to the coil Primary and expect output voltage on the secondary side. No, or the output voltage, the lower the transformer winding has open or shorted winding. Look for any evidence of overheating, such as black or dark areas or a burning smell.

On the way to test a power transformer, which is somewhat complicated. Can be applied AC voltage of the computer and wait for the start of desire in the secondary without connect to load otherwise the voltage will happen (because it has eliminated all the secondary payload) and blow the power section consists of the power FET, IC, etc. Switch Mode Power supply designed to operate with a load, then CONVERT LINEAR test can be unloaded.

The best way to test a switch on the power transformer is the first way to remove it from the Commission. Verify that the primary winding and secondary winding failures are extremely rare. How can we know the primary? Draw the filter cover large pin more positive the circuit goes. Attend one of the processor pins. Then, find the center pin FET drain power and it takes you to another number of processors. These two pins is the primary winding of the transformer. Verification resistance of the primary winding can not reveal whether it is open, but can not verify the developed short of liquidation. By a ring test whether short-circuit or not. In turn, runs in the primary winding can cause the power section of a sudden.

The cheaper the tester sounds I came across is Dick Smith Meter lOPT or flyback tester. Simply connect the probes to the primary winding and result is immediately visible on the LED bar graph. 4-8 bar represent a good winding, 1-2 bar represent short part and if the light is off it means a very short in the coil. In addition to checking the processor can be used to check B + coil, horizontal yoke coil and flyback primary winding and ballast (choke).

The ring test is an expensive Sencore equipment. Sencore LC102 capacitor and also LC103C also controls be able to check all types of liquidation. What low-voltage transformer, high voltage transformer, current transformers, pulse transformers, electric transformer, custom transformer this equipment will be able to check and test it.

If you do not want to invest on this tester can use a bulb check. Remove one of the spur of the primary winding and connect a 60 watt bulb. One end of the circuit, while the other to pin the processor. If the bulb and will not suspect a shunt winding and if the light goes on Regulation Not bad.

Transforming the repair is not easy and requires a good ability to do so. Most processors preferred repairer to rewind largest colony, such as fans, alternator and starter motor. Food processor voltage mode to rewind a bit difficult because the small size and low price.
