Abstract
A new scheme of symmetric multilevel inverter is proposed that could reduce the switch numbers, conduction losses, and costs. A novel switching algorithm based on selective harmonic elimination PWM scheme has been introduced to control the voltage balancing of the dc link capacitors. In this way, all of the voltage levels can be created in the inverter output with only one dc power supply. The visibility and effectiveness of the proposed strategy has been verified through various simulation results.
