i. introduction multilevel inverters are increasingly being used in high-power medium voltage applications due to their superior performance compared to two-level inverters, such as lower common-mode voltage, lower dv/dt, lower harmonics in output voltage and current, and reduced voltage on the power switches. among various modulation techniques for a multilevel inverter, space vector pulsewidth modulation (svpwm) is an attractive candidate due to the following merits. it directly uses the [登陆后可查看全文]
