The Right Way To Discharge Capacitor In Switch Mode Power Supplies
|
Switch mode power supply contain some large filter capacitors that can hold dangerous charges even if the unit has not been used for several days. Learn the fast and simple ways to discharge the big filter capacitor in switch mode power supplies... |
|
Current sense resistor is usually located in the switch mode power supply section. Find out the cause of low output voltage by knowing on how to accuratey check a current sense resistor. |
|
There is something good about esr meter because besides electrolytic capacitor it can be use to measure other type of capacitors such as the non polarity capacitor. |
|
Linear transformer mostly used in radio, project kits, VCD and etc while switch mode transformer can be found in Monitor, Tv, Fax and so on. Learn the right way to test and check a linear and switch mode power transformer. |

Many technicians are confused on how to really read a zener diode code. There are many types of code number indicated on it's body. The look and shape of a zener diode sometimescan be mistaken to be a normal signal diode. |
|
Testing diodes is different from testing a resistor because you need a skill to do it. If you do not know or wrongly test a diode you will be unable to repair the equipment. A bad diode you think it is good. This will definitely waste your precious time. |
