摘要

Nowadays the energy infrastructure of the whole world is broken and it leaves large-scale power outages in many areas. The main goal of producing electricity will in this case be given the same importance as that of optimizing circuit parameters. The fact that a number of important electronic devices and machines rely on direct electrical feed makes academicians focus on enhancing rectification technologies to enable interaction with induction-type engines. More importantly, the development of rectifiers has aimed in the reduction of conduction losses, minimization of source side harmonic distortion, and improvement of power-factor characteristics. In these limits, alternating current to direct current (AC-DC) converters, and in particular continuous conduction mode (CCM) converters, become of essential concern. The converter under analysis is a bridgeless, CCM converter which is used as an input current regulator and an output voltage regulator. The bridgeless converter is compared in terms of performance with a conventional bridge-supported rectifier using modelling and simulation. Results show that the bridgeless mode produces less conduction losses, less input-current harmonics and better input power-factor. The bridgeless concept applied to an induction motor drive shows significant efficiency improvement compared with those of traditional bridge rectifiers.
