Abstract

With growing technologies, the exhaustion procedure of fossil fuels occurs at a faster pace. At the moment, research area mainly emphasizes on efficient utilization of the renewable energy resources. To achieve this, many converters have been developed over the years, but there exist some disadvantages in almost all the topologies which may be related to either the gain of the converter, or the overall efficiency, or the voltage stabilization, or the ripple content etc. In this paper, an active clamped, high gain, hybrid, forward boost converter has been developed which will attenuate the abovementioned problems that are observed in the conventional converters. In the proposed converter topology, two modes are attainable, which maybe further controlled using a push button only. One of the modes involves the closing of the push button, wherein the input voltage will be less and with the help of a less duty cycle, expected voltage is acquired. This mode is known as a hybrid mode. In the second mode i.e. boost mode, required output voltage is obtained from the lower input voltage. In both the modes, high gain and high efficiency are obtained from the converter. The converter simulation and the required results are furnished and provided.
