Switching power supply and ups solar power application

Switching power supply and UPS solar power: switching power supply relativelinear power said he input directly to the AC into DC, then shakes the function of the circuit at high frequency, UPS solar power switch tube control the on-off of the electric current, the formation of high frequency pulse current. In theinductor (high frequency transformer) under the help of the low voltage DC power, solar power and switch power supply output stability of UPS. Because the core size and computer ups power supply his work frequency transformer is inversely proportional to the square of the smaller, higher frequency core. This can greatly reduce thetransformer, UPS of solar power. The power to reduce weight and volume. But due to its direct control of DC, UPS solar power so that the efficiency of this kind of power is much higher than the linear power supply. Switching power supply so as to save energy,ups solar power so it is favored by people. But it also has the disadvantages of complex circuit,industrial ups power supply is difficult to repair, switching power supply, circuit pollution. Power supply noise, not suitable for some low noise circuit.

Effect and significance of UPS home?

  Due to the development of information technology, network has become an indispensable part of people's lives and work, power supply reliability digitalcomputer network has become a key, and the reliable power supply room is the priority among priorities, UPS home is in order to solve the uninterrupted power supply and setting, UPS home of the three basic functions: voltage regulator, filter, can not be interrupted. In the city power, it is the regulatorand filter function, to eliminate or weaken the power interference, ensure the equipment work normally; in the city electricity is interrupted, it can take the DC power supply part of its battery pack, switching power supply to provideDC into AC load used for perfect among them, the city power to battery power is usually time to switch, so that the load equipment in does not feel any change at the same time to keep running, real guarantee ofuninterrupted operation of equipment.
