N2 - A new scheme for high boost trans-z-source inverter with continuous input current is proposed. Because of the high boosting capability of the proposed inverter, the modulation index will be higher with lower shoot-through duty ratio. Higher modulation index will lead to improved total harmonic distortion of the output voltage. This topology has one inductor, three diodes, two transformers, and three capacitors. Comparison between the new schemes with the previously proposed trans-z-source topologies is made based on the voltage stresses on capacitors, efficiency, and voltage boost factor. To verify the effectiveness and validity of the new inverter, experimental and simulation results are provided.
