Abstract

Conversor CA-CC Trifásico Isolado em Alta Freqüência por único Estágio. O presente invento realiza a transferência de potência da rede trifásica para a carga de maneira isolada por meia de um retificador trifásico PWM tipo Buck conectado diretamente a um transformador forward/flyback, onde estas duas estruturas compõem um conversor CA-CC de único estágio. A ponte retificadora trifásica do tipo Buck proporciona a tensão retificada modulada em alta freqüência para o enrolamento primário do transformador. O enrolamento secundário, ou forward, é o responsável por maior parte da potência transferida à carga e o enrolamento terciário, ou flyback, desmagnetiza o núcleo do transformador regenerando esta energia à carga. A modulação por largura de pulso senoidal em três níveis e a utilização do filtro de entrada proporcionam a este conversor um fator de potência praticamente unitário e uma reduzida distorção harmónica total para as correntes de entrada.Single-phase High Frequency Isolated Three-Phase AC-DC Converter. The present invention performs power transfer from the three-phase grid to the load in isolation by means of a three-phase PWM Buck rectifier connected directly to a forward / flyback transformer, where these two structures make up a single-stage AC-DC converter. The Buck three phase rectifier bridge provides the high frequency modulated rectified voltage for the primary transformer winding. Secondary winding, or forward, is responsible for most of the power transferred to the load, and tertiary winding, or flyback, degausses the transformer core regenerating this energy to the load. Three-level sinusoidal pulse width modulation and the use of the input filter give this converter a practically unit power factor and reduced total harmonic distortion for the input currents.
