摘要
为了进行超导磁体的交流长样实验,根据系统研究目标,提出了一种三相电压型PWM整流器与单相全桥逆变器相结合的电路结构,并分别讨论各个部分的控制策略,然后对电路主要器件参数进行了详细设计,最后利用Matlab/Simulink工具对整个系统进行电路仿真,得到了较理想的负载电流输出波形。
To do a long superconducting magnet AC sample experiments, according to the research objective of the system, we proposed a type of circuit structure which combinesd a three - phase voltage - type PWM rectifier with a single - phase full - bridge inverter, and various parts of the control strategy were discussed in this paper. The parameters of the main components of the circuit were designed in detail. Finally we made use of the matlab / simulink tools for circuit simulation of the entire system, which has obtained an ideal output waveform of the load current.
