Hybrid DC Boost Converter for Efficient Voltage Regulation and Dimming Control

In the recent decade, many electronic circuits board require different voltages for their proper working. Since the functioning device needs to be compact; hence it will not be possible to place individual voltage source for each component, hence an effective power electronic-based boost converter simplifies the problem by providing a wide range of system gain in order to achieve the desired value. In this paper, a high gain boost converter is explained, which is the merger of 3 different boost converting techniques. They are incorporated in such a fashion that the stress on all semiconductor devices is very less, and the overall voltage gain is very high. The another advantage of this hybrid converter is that the high voltage gain is achieved with a low value of duty cycle. To validate the analysis of the converter, a hardware is present with input 9 V which gives an output of 120 V on 0.68 duty cycle with 36 W power input. The presented hardware has LED load and the converter here is used as an LED dimming control by varying duty cycle.
