Desenvolvimento de um módulo estabilizador de tensão empregando o conceito de transformador híbrido

Abstract

Depending on the quality of the energy in rural environments, or environments that require the use of electrical extensions from the point of delivery to the point of use, it can be verified that there is instability. As well as a voltage drop, taking into account that in these casesit is unlikely to be used at the point of delivery, where the variation is small and controlled. In environments that use low power, and low complexity equipment, this analysis or attention is not available, but it directly affects the behavior, useful life and power of the equipment. This work proposes the use of a voltage stabilizer module, using a hybrid transformer and two converters, one being used as a rectifier, and the other as an inverter, so that voltage control can be carried out, thus causing a minimum variation in the output of the device, which will be within accepted standards, which will not affect the equipment. It is also possible, in addition to stabilizing the output voltage to appropriate standards, to achieve an improvement in power factor through a current control, in the same module.
