摘　　要：设计一种改进的市电闭环供电系统,提高系统的整流能力和电力稳定控制能力。传统的市电闭环供电系统采用单相桥式整流控制设计方案,不能有效满足市电稳定控制的需求。提出一种基于动态增益控制的市电闭环供电系统设计算法。进行市电闭环供电系统设计总体模型设计,构建单相桥式整流电容滤波电路,得到供电系统机组转动惯量通电线圈在高频下会产生欧姆损耗和辐射损耗,构建电闭环供电系统的定子结构和电机结构,分析供电系统的磁密分布特性,进行动态增益控制算法改进设计。仿真结果得出,设计的市电闭环供电系统能有效提高供电系统的转矩,进而提高输出功率,获得较高的闭环控制增益。An improved design of city electric closed-loop power supply system, improve the system of rectifying ability and stable power control capability. City Electric closed-loop power supply system using the traditional single-phase bridge rectifier control scheme, a receiver will high frequency sinusoidal alternating current when received, it cannot effectively meet the city electricity demand stability control. An electric City closed loop power supply system design algorithm based on dynamic gain control is proposed. Electrical design of city design of the overall model of closed loop supply system, construction of single phase bridge rectifier capacitor filter circuit, get the inertia unit power supply system of coil in high frequency can be generated under the ohmic loss and radiation loss, stator structure and motor structure electric closed-loop power supply system structure, analysis of the power supply system of magnetic density distribution characteristics, dynamic gain improvement of control algorithm design. Simulation results show, the city power close loop power supply system design can effectively improve the torque of the power supply system, so as to increase the output power, the gain obtained higher closed loop control.
