Sa pag unlad ng teknolohiya ng impormasyon, Inverter Power Supplies ay higit pa at mas malawak na ginagamit sa pagbabangko, mga mahalagang papel, militar, medikal na, aerospace at iba pang mga patlang. The early inverter power supplies only required that their outputs could be uninterrupted, voltage stabilized, and frequency stabilized. .

Gayunpaman, in addition to these requirements, today's inverter power supply must also be environmentally friendly and pollution-free, na ang ibig sabihin ay, a green and environmentally friendly inverter power supply. Kasabay nito, with the development of network technology, higher requirements have been put forward for the network function of inverter power supply.
High-performance inverter power supply must meet:
①High input power factor, low output impedance;
②Shaanxi speed’s transient response and high steady-state accuracy;
③High concealment, mataas na kahusayan at mataas na pagiging maaasahan;
④Electromagnetic interference from Di;
⑤Intelligent;
⑥Perfect network functions. Obviously, the realization of these requirements cannot be achieved without digital control technology.
