Mit der Entwicklung der Informationstechnologie, Wechselrichter-Stromversorgungen werden im Bankwesen immer häufiger eingesetzt, Wertpapiere, Militär, medizinisch, Luft- und Raumfahrt und andere Bereiche. The early inverter power supplies only required that their outputs could be uninterrupted, voltage stabilized, and frequency stabilized. .

Jedoch, in addition to these requirements, today's inverter power supply must also be environmentally friendly and pollution-free, das heißt, a green and environmentally friendly inverter power supply. Gleichzeitig, 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, high efficiency and high reliability;
④Electromagnetic interference from Di;
⑤Intelligent;
⑥Perfect network functions. Obviously, the realization of these requirements cannot be achieved without digital control technology.
