摘要
during one period of PWM four switches commutations occur, compared with six commutations in sinusoidal PWM, that reduces dynamic losses of invertor. Vector PWM maximally uses voltage reserve of direct current link, that is 15% more than for sinusoidal PWM. For invertors with bootstrap feeding of upper switches' drivers, that is getting power from bootstrap capacity or floating source, it is necessary usage bounding to lower bus, that is chose sense of rotation of basis vectors so that invertor uses zero state 000.
