Abstract：Space vector pulse width modulation（SVPWM）strategy is one of the key technologies for threelevelinverters. However，conventional three-level SVPWM often experiences neutral point potential（NPP）oscillation and high switching loss when addressing the neutral point potential balancing issue. To tackle thischall...
