摘要
在数学建模与仿真实验的基础上搭建一台三相逆变电源,分析三相逆变电源在空载、纯阻性负载、纯感性负载的情况下逆变输出电压、电流波形图,并对该系统在突增负载与突卸负载的情况下输出电压进行了研究。研究分析表明:该控制策略使得逆变电源系统输出电压稳定,无明显波形失真与波形畸变、谐波含量少、系统稳定性强,并具有良好的鲁棒性、抗干扰性与动态响应性能。
Based on modeling and simulation,a three-phase inverter power supply was built.The inverter output voltage and current waveform were analyzed under the conditions of no load,pure resistance load and pure inductive load,and the influence of sudden loading on and loading off on output voltage for the system was studied also.The analysis showed that the applied control strategy made the inverter power supply system output voltage stable with small waveform distortion,and the system had the advantages of good stability,good robustness and anti-interference and dynamic-response performance.
