摘要: Nine-switch inverters were designed by sharing three-switches to realize dual-outputs, which are normally realized two three phase with 12 power semiconductors. Therefore, its modulation strategy is very complex and hard implement. For this reason, a simplified modulations for the nine-switch inverter proposed. Based on switched system model, m-modes controllability of first proposed design space vector pulse width (SVPWM) strategy. Compared conventional SVPWM strategies, newly switching scheme cannot only reduce half operating modes but also frequencies. It significant since it can simplify control, increase efficiency economy cost. Finally, prototype verify
