Modeling and control of a single-stage current source inverter with amplified sinusoidal output voltage

Alternative energy sources has been attracting great interest in the area of static converter development. This fact is related to issues like sustainability and the world environment, which is contributing to viability of this type of energy source. The main challenge is to develop systems that transform this DC energy in AC. Within this subject, this paper focuses the establishment of a new control strategy applied to a step-down/step-up single-stage inverter with imposed waveforms of input inductor current and output voltage. The proposed control strategy provides high voltage gain without using high frequency transformer, which contributes to weigh and size reduction of the proposed DC-AC converter structure. Theoretical analysis are presented and corroborated by experimental results of a 180W laboratory prototype fed by a fuel cell.
