The Harmonics control of any inverters can be decided by the PWM incorporated for the switches. In recent years the carrier and reference modification based research is going on the inverter field. This paper suggests that the alteration of carriers and references of the three phase voltage source inverter enhance the ability to decrease the harmonic content.This enhanced realization deals with the carrier and reference modification arrangement for three phase voltage source inverter through amalgamating the boosted reference and random triangular carrier. The boosted reference is the addition of sine reference with injection of 1/3rd of reference amplitude (3f_s) in the middle portion of the reference wave. i.e., $\frac{\prod }{3}$ to $\frac{2\prod }{3}$ and $\frac{4\prod }{3}$ to $\frac{5\prod }{3}$ . The proposed PWM scheme use two carriers, one is Triangle wave and another one is inverted Triangle wave. The process of selecting the winning carrier among the two triangle carriers is purely based on the LFSR technique. The spectral quality of the induction motor drives has improved by the random carriers. The simulation and experimental values are proving the validity of the PWM method. The PWMs are generated by using parallel processing enabled FPGA processor.

任何逆变器的谐波控制都可以通过开关内置的PWM来确定。近年来，基于载波和参考修改的研究正在逆变器领域进行。本文提出通过改变三相电压源逆变器的载流子和参考点来增强降低谐波含量的能力。这种增强的实现方式是通过将升压参考值和随机数相结合来解决三相电压源逆变器的载流子和参考值修改方案。三角形载体。增强参考是在参考波的中间部分注入正弦参考，并注入参考幅度的三分之一（3f _s）。IE，$\frac{\prod }{3}$ 至 $\frac{\mathrm{2个}\prod }{3}$ 和 $\frac{4\prod }{3}$ 至 $\frac{5\prod }{3}$。所提出的PWM方案使用两个载波，一个是三角波，另一个是倒三角波。在两个三角形载波中选择获胜载波的过程完全基于LFSR技术。随机载波改善了感应电动机驱动器的频谱质量。仿真和实验结果证明了PWM方法的有效性。通过使用启用了并行处理的FPGA处理器来生成PWM。
