Abstract
Multilevel inverters are preferred for variable speed drives due to its improved output voltage profile , less low order harmonic content and low dv/dt requirements for the devises etc;. But the conventional multilevel voltage space vector structure has a hexagonal profile and it introduces the low order 5th and seventh harmonics especially in the overmodulation region. In this respect dodecagonal voltage space vector structure with increased modulation range and suppression of the fifth and seventh order harmonics is a viable alternative for the conventional hexagonal structure for the voltage space vector structure, for PWM control. The dodecagonal voltage space vector structure generation for an induction motor drive with a split-phase structure will be introduced in the first part of the lecture and then it will be extended to the normal three phase IM drive using a switched capacitive H-bridge acting as a 5th and 7th order harmonics, throughout the modulation range, in this talk. The switched capacitive filter with a capacitive fed H-bridge will only supply reactive energy and the capacitor voltage can be balanced during the PWM control without any complexity. This will also enable the main inverter, delivering the active power to the load, to be switched with low PWM switching frequency.
