তথ্য প্রযুক্তির উন্নয়নের সাথে সাথে, বৈদ্যুতিন সংকেতের মেরু বদল পাওয়ার সাপ্লাই বেশি এবং আরো ব্যাপকভাবে ব্যাঙ্কিং ব্যবহৃত হয়, সিকিউরিটিজ, সামরিক, চিকিৎসা, মহাকাশ এবং অন্যান্য ক্ষেত্র. The early inverter power supplies only required that their outputs could be uninterrupted, voltage stabilized, and frequency stabilized. .

যাহোক, in addition to these requirements, today's inverter power supply must also be environmentally friendly and pollution-free, এটাই, a green and environmentally friendly inverter power supply. একই সময়ে, 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.
