大功率變頻電源的優化設計

摘要：針對大功率變頻電源出現的實際工程問題提出了獨特的優化方案，主要應用了迭層母線；增加了抗偏磁電路；改進了集中過流保護電路和吸收電路。經實踐檢驗證明，采用了以上改進方案，提高了大功率變頻電源的可靠性，使整機性能大大提高。 敘詞：迭層母線 變頻電源 過流保護 抗偏磁電路 Abstract：I will raise my feasible solution to improve the high-power variable-frequency power sources according to some practical problems. I use the laminated　busbar　and anti-bias circuits, After that I improve current feedback circuit and absorption circuit. It has been proved by practical test that the reliability　of high-power variable-frequency power sources is advanced to a higher degree definitely.
