6-Mode SVPWM for Nine-Switch Dual-Output Inverter
Manufacturing industries such as textiles, paper, and steel require high-performance control of multiple variable-frequency motors simultaneously. Normally, one motor is controlled by one inverter. However, with the continuous improvement of the cost performance requirements of the variable-frequency system, driving multiple motors by only one inverter has become a development trend, thus the nine-switch inverter with two outputs was proposed. In this chapter, the m-mode SVPWM method is applied to the nine-switch dual-output inverter, which not only verifies and expands the application of m-mode SVPWM, but also puts forward a novel SVPWM technique different from the existing ones to further enhance the performance of inverters.
