I wonder if that article is referring to PWM (pulse width modulation) wave synthesis? Works OK in AC drives, but the motor windings need to have much better insulation due to 'ringing', which causes induced voltage spikes exceeding the insulation breakdown rating. Still, the power efficiency is pretty good.
