This paper mainly studies the parallel technology of the single phase inverter and presents a parallel strategy in which there is no power line connection but digital line connection among the inverter modules . this control strategy can be easily realized and the control effect is good 本文主要研究单相逆变器并联控制技术，在所提出的逆变器并联控制策略下各并联模块间只有数据连线，无模拟连线，而且控制简单，环流抑制效果较好。
