Abstract

"In most power electronic systems, the instantaneous input and output power vary by time and are not exactly identical with each other. Hence, providing a good match between them is a complicated task to deal with if not impossible. Furthermore, due to the wide variation range of the processed power, the overall efficiency of the system is not high. The solution is to hybridize the system using an energy storage unit like in hybrid electric vehicles, power factor correction systems, and photovoltaic systems. Multi-input converters play a key role in such hybridized systems, where it is required to have more than one power source...In this thesis, a systematic approach to derive several new double-input converters using H-bridge cells or single-pole triple-throw switches as building blocks is proposed. Different operating modes and the switch realization of the new converters are obtained and their corresponding voltage ratios are derived. Bidirectional power flow is also considered. All of the proposed converters consist of only one inductor; hence, the number of passive elements that are required is reduced. The operating characteristics of the new converters are verified using simulation results"--Abstract, page iii.
