Parallel DC/AC Converters under Connection/Disconnection of Power Modules

Abstract

Paralleling converters is normally employed to increase power capacity in different applications, such as autonomous micro grid systems and unininterruptible power supplies. These systems share the current between the different converters, but it must be in an equalized manner, no matter different type of loads or conditions. This paper propose an alternative to operate parallel inverters, the proposal is able to reconfigure its operation by itself under connection or disconnection of inverter modules, and the system keeps uniformly shared the current between the power units. Selected control strategy is sliding mode control due to its robustness under large uncertain variations. Operation and experimental results are shown.
