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...
