摘　　要：阐述一种基于双逆变器的载波交错技术(CPST),通过上下变流器的开关时钟信号寻优,使部分谐波转换成相间谐波环流和降低了电压波动幅度。实现减小直流环节电容电流谐波,延长了直流环节电容器的使用寿命。通过Matlab/Simulink建立仿真模型,验证了该控制策略的有效性。This paper describes a carrier interleave technique(CPST) based on dual inverters. By optimizing the switching clock signal of the up-down converter, some harmonics are converted into interphase harmonic circulation and voltage fluctuation amplitude is reduced. The harmonic current of DC capacitor is reduced and the service life of DC capacitor is extended. Finally, a simulation model is established by Matlab/Simulink to verify the effectiveness of the control strategy.
