逆变器的开关由从调制技术产生的控制信号操作，该调制技术用于减少总谐波失真以改善输出电压质量。在本文中，三种调制技术的基础上，多载波电平移位PWM已实现，本文的目的是比较这三种技术，了解他们对逆变器的输出电压质量的影响。三种调制技术是正弦参考同相配置技术（S-IPD）、正弦参考交替反相配置（S-APOD）和正弦参考反相配置（S-POD）。将这些技术应用于单相半桥五电平二极管箝位逆变器，在不同的工作条件下进行了仿真。该研究已经通过使用MATLAB/Simulink仿真和在实验室中的设置实验来实现。模拟和实验结果之间的比较，并进行了讨论。
The switches of the inverter are operated by the control signal generated from the modulation techniques which are used to reduce the total harmonic distortion to improved output voltage quality. In this paper three modulation techniques based on a multicarrier level shifted PWM have been implemented, and the aim of this paper is to compare these three techniques to know how they effect on the output voltage quality of the inverter. The three modulation techniques are Sinusoidal Reference In Phase Disposition technique(S-IPD), Sinusoidal Reference Alternative Phase Opposition Disposition (S-APOD) and Sinusoidal Reference Phase Opposition Disposition (S-POD). These techniques are applied to the single phase half bridge 5-levels diode clamped inverter under different operation conditions. The study has been implemented via simulation using MATLAB/Simulink and setup experiments in the lab. The comparison between the simulation and experimental results are provided and discussed.
