摘　　要：针对农用小功率三相交流电机不易获取三相电源而无法广泛应用的问题,设计了一种在农用220 V单相交流电源的情况下,可输出电压幅值可无级调控的三相交流变频系统,能够实现小功率三相交流电机在农用单相电源的情况下广泛地使用。实验结果表明:当输入220 V交流电源时,可输出三相可控的交流电源。系统硬件设计合理,为农用小功率电源的变频控制的广泛应用提供了技术支持。For the problem that the agricultural low-power three-phase AC motor cannot be widely used because the three-phase power supply is not easy to get,one kind of three-phase AC variable frequency system which can output stepless regulation voltage amplitude was designed under the condition of agricultural 220 V single-phase AC power supply,through which the low-power three-phase AC motor can be widely used under the condition of agricultural single-phase power supply.The experimental results show that the controllable three-phase AC power can be output when 220 V AC power supply is input.The reasonable design of system hardware provides the technical support for the wide application of variable frequency control of agricultural low-power supply.
