– This paper is the second of two parts and reviews results of a recently completed project based at the University of Aveiro, UMIST and the University of Lancaster. This research represents a fundamental investigation of the potential of using electromagnetic inductance measurements for industrial tomographic applications. This second paper concentrates on(More)
— This paper presents a three-phase Buck-Boost rectifier operating in continuous conduction mode (CCM). The proposed circuit provide, with a single-stage, output voltages lower or higher than input line voltage peak. The circuit has three operating modes: Boost, Buck and Buck-or-Boost. The transition between the operation modes occurs naturally, without(More)
– This paper presents a three-phase Buck-Boost rectifier operating in discontinuous current mode (DCM). The main advantage of the proposed circuit is to provide, with a single stage, output voltages lower or higher than input voltage peaks. The command is very simple, with all switches simultaneously powered by the same pulse. The control of the structure(More)
