초록
This paper deals with the parallel operation of inverters. To enlarge capacity of inverter system and reduce current ripples on inverter output side, two or more inverters are operated in parallel. Up to now six-step inverters and sinusoidal PWM inverters are considered in parallel operation, but using space-vector PWM inverters we can get many advantages of reducing ripple current energy and torque ripple and so on. As we can choose effective voltage vectors more freely than single operation, inverter output current ripples can be reduced by shifting beginning and end point of switching state back and forth.
