摘要:
传统的H 桥级联型多电平逆变器SHEPWM 技术多用于各单元直流侧电源完全相等的情况,但在实际应用中电源电压可能会产生一定的偏差,使得特定谐波消除效果变差。针对这一问题,提出了一种基于直流侧电压不均衡的多电平逆变器SHEPWM 技术,以七电平逆变器为例,取3 种不同电压值情况,利用多种群遗传算法求解建立的非线性方程组得出对应的开关角度解。对3 种不同电压值情况下的开关角度轨迹进行了分析,对调制比0. 65 ~ 0. 85 区间内出现的多解情况进行了讨论,对比不同解时消谐效果的差异,为不同要求场合下消谐角度的选择提供了参考。仿真和实验结果证明了该控制技术的可行性和可靠性。
Abstract:
Traditional SHEPWM technique is usually applied in was cascaded H-bridge inverters,in which DC sources were completely equivalent cells. But in the practical application,the power supply voltage may produce a certain deviation,which leads to the negative effect of harmonic elimination . A novel SHEPWM technique for Cascade H-bridge multilevel inverters with Non-Equal DC Sources was proposed.Taking a seven-level inverter as an example,three cases of different voltage were selected,the established
nonlinear equations were solved and switch angles solution were obtained by using multiple population genetic algorithm. The switch angles trajectories under three cases were researched. For the solution trajectory bifurcation,two groups of solutions were discussed when modulation was between 0. 65 to 0. 85 and the different harmonic elimination effect between different solutions was contrasted. It provides a reference for the choice of harmonic elimination angle for different requirements. Simulation and experimental results verify that the control technology is feasible and reliable.
