摘要
针对五开关级联H桥逆变器提出一种新的调制策略,该调制策略是在载波移相原理的基础上,对调制波与载波比较得到的脉冲信号作进一步的处理,之后作为开关器件的脉冲触发信号。采用该调制策略,不仅能够实现载波移相调制的功率均衡效果,而且能够达到载波移相调制的良好消谐效果,最后通过MATLAB/simulink搭建了三单元五开关级联H桥逆变器仿真模型,通过仿真结果验证了理论分析的正确性。
A new modulation strategy for five-switch cascaded H-bridge inverters is proposed, which is based on the principle of carrier phase shift, and further processes the pulse signal compared with the carrier wave. It acts as the pulse trigger signal of the switch device. This modulation strategy can not only achieve the power equalization effect of carrier phase shift modulation, but also achieve the good harmonic elimination effect of carrier phase shift modulation. Finally, a simulation model is built by MATLAB/simulink. The correctness of the theoretical analysis is verified by the simulation results.
