Switching power supply is the preferred 220V AC power rectifier with about 300 volts for the DC, and then use the electronic switching circuit with switching power transformers, rectifier output DC output for the application. The main advantage of switching power supply is high efficiency, generally up to 80% to 90%, small size, light weight, voltage regulator performance. But the line is more complex. Generally used in the power requirements of relatively high places, such as: color television sets, radio and television transmitters and some of the more demanding on the power of electronic equipment.
The advantage of using a power transformer is that the circuit is simple and can be made by beginners alike. The disadvantage is inefficiency, generally only about 50%, large size, the regulator performance somewhat less. In less demanding situations with the more common use, such as: power amplifiers, black and white TV, amplifiers and so on.
