Linear Power Supply

Linear Power Supply
Every electronic circuit will work as good as its power supply. However this is often overlooked. There are two main families of power supplies: the linear power supply and switch mode power supplies.  Linear power supplies are easier to manufacture and to troubleshoot. But they have the disadvantage (especially for high power), the circuit is more complicated with the results of less power and heat faster than the switch mode power supply. (more…)

Current Source / Regulator

Current Source / Regulator
The Current Source/Regulator circuit powers the load through the regulator's input rather than its output. Since the regulator's output sees constant dummy load R1, it attempts to consume a constant amount of current, regardless of what the  voltage across the actual load really is. Therefore, the regulator's input works as a constant current source for the actual load. (more…)

Computer Power Supply Repair

Computer Power Supply Repair
Actually power supply repair is rarely - less expensive to replace it with new. A defective power supply is usually thrown away, unless, of course, it is not a quality or expensive. In the latter case it is better to send it to a firm that specializes in the repair of power units and other components. (more…)

Computer Power Supply Features

Computer Power Supply Features
There are some features of the computer power supply which should be consider when buying or replacing your old power supply. Here is a power supply features to be considered: (more…)

Computer Power Supply Options

Computer Power Supply Options
The quality of power supply depends not only on power output. Experience shows that if a room is more than one computer and electrical network quality is low (often disappears voltage noise occurs, etc.), systems with powerful power supply systems work much better with low-cost units to be installed in some models of low-class .
