摘　　要：由于数字式触发电路定时精度正确，对称度好，在变流装置中应用广泛。实验表明：三相无源逆变器采用数字触发电路后效果良好。文章阐述了在设计该触发电路中的几个问题，即脉冲分配器和主电路的定相，防止无效循环，以及脉冲列输出等内容。Because of its precise timing and fine symmetry the digital trigger has wide applications in various converters. The experiment has proved that the digital trigger used in the 3-phase passive inverter produces a fine result. Explained several problems in the trigger design as well as their solutions. They are: fixing phase in the pulse divider and main circuit,preventing noneffective circulation, outputting pulse order and so on.
