Study and implementation of boost-derived hybrid converter with simultaneous DC and AC outputs

摘要

In this paper a work is done on the new topology of converter that can convert concurrently into DC and AC outputs from a solitary dc input in a single stage. This topology can be achieved by using VSI bridge network in place of controlled single switch of step-up converter. This paper investigates the use of single step-up (boost) stage architecture to supply hybrid loads. This new hybrid converter topology needed less switches in respect of conventional method. The suggested topology will also improve the reliability, which is an outcome of its inherent property of shoot through at the VSI stage. The strategy of controlled PWM is being analyzed and modified in accordance to achieve the desired duty cycle to examine the behavior of BDHC topology. The integration of solar panel and fuel cell stack as a dc input source has been prepared in Matlab/Simulink and its execution is done to authenticate the working of BDHC topology. The comparison of various Simulink models has been performed for different duty cycle to study the output nature of different types of loads.
