Abstract
© 2016 IEEE. Conventional three-phase diode or controlled rectifiers generate current harmonics which affect power quality of distribution networks. This paper presents a novel topology with a front end Modular Multi-Parallel Rectifiers (MMR): Active DC link current controllers are utilized for each rectifier connected to a common DC link capacitor which can reduce line current harmonics emissions significantly. In the proposed topology, two current sensors are utilized in DC link legs to reduce switching ripples of the DC link currents. Analysis and simulations have been carried out to verify the proposed topology and operating modes.
