六相永磁同步发电机的整流稳压电路仿真

Six-phase Permanent Magnet Synchronous Generator Voltage Regulator Rectifier Circuit Simulation

针对六相永磁同步发电机励磁不可调,转速的变化和负载电流的变化都将造成输出电压不稳定的缺点,对六相永磁同步发电机发出的六相交流电采用带平衡电抗器的双三相全控桥并联的开关式稳压整流电路进行整流,控制方式采用闭环控制,使得整流输出直流电压恒定,不随着发电机转速和负载电流的变化而变化。利用Matlab的Simulink和PSB两个工具箱建立了六相永磁同步发电机的整流稳压电路仿真模型对该整流电路进行了仿真。仿真结果表明该稳压整流电路输出直流电压值不随发电机输出电压变化而变化,负载电压稳定时间快、无尖峰、脉动小。

For the six-phase permanent magnet synchronous generator excitation was not adjustable, speed changes and changes in load current would cause the output bridge rectifier with equilibrium reactor circuit was used to voltage instability, the two-phase full-controlled solve the problem, control method used closedloop control to make the rectifier output DC voltage constant, the output DC voltage will not change with the generator speed and load current changes. Then used the Matlab toolbox Simulink and PSB extablished six- phase permanent magnet synchronous generator rectifier voltage regulator circuit simulation model for the simulation of the rectifier circuit. Simulation results show that the regulator rectifier output DC voltage does not change with the generator output voltage, load voltage stabilization time soon, no peak, pulse small.
