摘　　要：提出通过提高定子双绕组感应发电机控制绕组与功率绕组的匝数比来升高控制绕组的电压,从而降低控制绕组励磁变换器电流的设计策略,同时可以省去功率侧的励磁电容器和控制侧的滤波电感,由此构成一种小电流励磁控制大电流功率输出的新型励磁控制系统。利用改进的粒子群算法对1台整流桥输出18kW、28V的样机在转速变比为1∶2.5的运行条件下进行了优化设计。结果表明,该优化设计策略有效降低了控制绕组励磁变换器的电流及系统的成本、体积和重量。The special design strategy that the minimal current converter can be used to control large current out-put is studied. When the output voltage of power winding is very low and the output current very high, the large winding turn ratio between the control winding and power winding is proposed to reduce the current of control winding. The excited capacitor of power winding and filter inductor of control winding can be canceled. The improved particle swarm optimization algorithm is presented for optimization design of a prototype of 18 kW with 28 V DC output under speed ratio of 1 ： 2.5. Design results show it is much benefit for reducing the capacity of control winding, the dimension, cost and weight of the system.
