From Table 2,it can be seen that there are redundant small vectors in regions 1-4,and the neutral-point potential can be controlled by introducing the distribution factor.Assuming that the voltages of the two capacitors are UC1 and UC2respectively at the end of the last switching cycle,the voltage difference between the two capacitors can be defined as
