Abstract:

This thesis proposed a family of dual-input single-output (DISO) step-up dc-dc converters exhibiting high voltage gain for grid-connected applications. The main advantage of the proposed concept is the common ground between input and output ports with a continuous input current profile at both input ports. Secondly, unlike previously reported solutions with discontinuous conduction (DCM) or pseudo-continuous conduction (PCCM) operation of the inductor, this thesis proposed a time multiplexed hysteretic control scheme (TMHC) to decouple the power-sharing among two input sources by keeping the inductor current in continuous conduction mode (CCM). Decoupling power sharing among the two input sources will remove unwanted transients and disruptions in the output. Lastly, this thesis proposed a fault-tolerant multiport converter where attention is given to the faults at the MOSFET level. This multiport converter can work in five different modes and reconfigure in case of a fault.
