單相逆變器的無互聯線并聯*

摘要：　　本文提出了一種逆變器的無互聯線并聯運行方案，采用此控制方案可以在兩機之間沒有任何信號連接線的情況下獲得良好的靜態與動態特性，從而使負載有功和無功功率得到了很好的均分,并且在兩臺3KVA的單相逆變器上進行了實驗驗證。 敘詞：逆變器；無線并聯；均流；下垂 Abstract：　　This paper presents a control technique which allows the wireless parallel operation of two single-phase inverters. Without control interconnection line between the two inverters，this scheme can achieves excellent characteristics both in steady states and in transient states，so active and reactive power are great shared . Experiments are presented to verify the theoretical discussion with two single-phase 3KVA inverters. Keyword：inverter, wireless parallel operation,current-sharing, droop
