General
We adopt special AC-DC change - over circuit  to  sense the output current and utput voltage of  the  commercial  power.  Through a  high - frequency  pulse width  modulator,  the  phase of  input  current waveform  and  voltage  waveform  becomes  the  same  and gets an input power  factor that is higher than  95%.  When the commercial power is normal ,  it  passes through AC-DC circuit and gets DC BUS DC voltage, then via inverter, the DC BUS turns into 220V AC output, finally,  the power supply that all the loads applied  is a kind of pure  sine  wave power supply that has proceeded voltage regulation, frequency  stabilization  and  noise  filtering. By  means  of  using superior IGBT for power inverting element thatshows  high  frequency  switching character, the working frequency of UPS inverter can reach tens  ofthousands hertz,  which  not  only  improves inverter working efficiency , but also improves the whole UPS  machine working
efficiency.
Performance
1. Controlled by microprocessor
Innovating software program control mode used by MOTOROLA microprocessor with strong application function  takes the place of complex hardware lines, it not only shows small volume and light weight, but also can reduce the fault rate of UPS.
2.Supply power for long time
Adopting charger with strong ability, adding battery at user's requirement and prolonging the reserve time, it is special for area where appears lack power supply for long time. 
3.Self-protection
With quite perfect self-protection design, either UPS overload, short-circuit, over low voltage of battery or high  temperature of UPS, the UPS will turn off automatically.
