Regulated switching power supply is applied in more and more people's lives, then how to classify regulated switching power supply ? Let us look at: 

 First, power inverter
   Inverter: generally refers to low-voltage direct current into alternating current high voltage or low voltage devices, the general Inverter comes with batteries, Computer City to buy the UPS power supply is an inverter power supply, but it brought the smaller battery, the computer can only work a few minutes after power failure or ten minutes, mainly used in a sudden power outage to continue for the computer power supply, we have the time to preserve unsaved data

   Linear power supply switch: There is a class of linear regulated power supply and transformer linear power supply is a different type of linear switching power supply, which the circuit patterns are single-ended flyback, single ended forward type , half-bridge, push-pull and full bridge. It is the fundamental difference and linear power transformer is that it does not work but work in frequency in the tens of kHz to several megabases Hz. Function control is not in saturation and cutoff, but work in the switch state; switching power supply, hence the name, switching power supply has the advantage of small size, light weight, stable and reliable; disadvantage relative to the linear power supply to the transformer that the larger the ripple, usually ≤ 1% VO (PP), good can be done several mV (PP) or less.

 Third, the AC power
   AC power: generally refers to the size and direction of change at any time intercropping periodic voltage or current, AC power supply of the standard provisions 220V50 Hz, Japan and other countries 110V60 Hz, power plugs and sockets used are different, alternating with time changes in the form of a variety. Different variations of the AC
