AbstractThe main difficulties facing the operation of parallel converters in DC microgrids (DCMGs) are load sharing, circulation current, and bus voltage regulation. A droop controller is commonly used to control current sharing among parallel DC–DC converters due to its simplicity. However, the values of droop parameters impact both bus voltage regulation and the error in current sharing among converters.

1 INTRODUCTION Restoring compromised, endodontically treated teeth could be challenging. The restoration of choice highly depends on various factors such as the amount of remaining structures, the shape of the tooth, its location within the dental arch which would impact the functional forces applied to it, and most importantly, the cosmetic requirements (Tait et al., 2005).
