數碼發電機整流開關控制電路設計

摘要：對現有數碼發電機中整流開關控制電路存在的不足作了討論，設計了一種新型的整流開關控制電路。在保證控制性能的前提下，利用一路觸發電路同時控制三相半控整流電路中三只晶閘管的導通與關斷，不需要同步電路，簡化了電路結構，減小了電路的體積和重量，降低了數碼發電機的成本。
敘詞：數碼發電機 三相半控整流 整流開關控制電路 Abstract：The article discusses existing deficiencies of control circuit for rectifier switch in digital generator, and in turn, designs new control circuit for rectifier switch. It applies one-phase trigger circuit to control the ON-OFF of the three thyristor for the three-phase half-controlled rectifier circuit without sacrificing its performance. The design does not need in-phase circuit, simplifies circuit structure, lowers the size and weight of the circuit, and reduces the cost for digital generators.
