资料介绍

为解决传统三相逆变电路平衡控制方法存在相位变化与波形输出一致性较差、输出稳定性较低的问题,提出基于混合逻辑算法的三相逆变电路平衡控制方法。根据混合逻辑理论,制定电路平衡控制的运算真值表,结合真值表对三相逆变电路的混合逻辑模型进行构建。采用混合逻辑模型对逆变电路系统中不均衡的负载结构进行分析,参照分析结果分别对电流和电压进行补偿。经过补偿后,调整电路中的线路阻抗和电流输出阻抗,实现对三相逆变电路的平衡控制。仿真结果表明,所提方法可以有效消除电路系统相位和波形的异常波动,电压输出波形与理想波形较为拟合,提高了相位变化与波形输出的一致性,同时提高了输出的稳定性。

In order to solve the problem of poor consistency and stability of waveform output and phase change in the traditional balance control method of three-phase inverter circuit,a balance control method of three-phase inverter circuit based on mixed logic algorithm was ording to the theory of mixed logic,the operational truth table of balance control is worked out,and the mixed logic model of three-phase inverter is constructed with the truth mixed logic model is used to analyze the unbalanced load structure in the inverter er compensation,the circuit impedance and current output impedance are adjusted to realize the balance control of the three-phase inverter ulation results show that the proposed method can effectively eliminate the abnormal phase and waveform fluctuations in the circuit system,and the voltage output waveform is more fitting with the ideal waveform,which improves the consistency of phase change and waveform output and as the stability of output.
