A new current-type magnetically coupled T-source inverter

This paper presents a new current-type magnetically T-source inverter (CMTSI) which employs a three-winding coupled transformer and a capacitor formed in T-shape to produce a higher current gain in comparison with current-type trans-Z-source inverter (trans-ZSI) and flipped Γ-source inverter (fTSI). The new impedance network exhibits a unique characteristic such that its current gain can be raised not only by increasing the first turn ratio α_mT but also by decreasing the second turn ratio β_mT of the coupled transformer. Some simulation results are shown to verify the theoretical analysis.
