| Abstract: | According to the basic principle of natural sampling SPWM,the software of SABER is used to simulate and analyse the factors that influence inverter output voltage.The factors include modulation coefficent,carrier wave frequency and dead time.By contrast the simulation and experimental results of inverter system,it can be verified the accuracy of simulation,and it shows that LC filter can filter the high frequency harmonic effictively. |
