This paper describes the design of trans Z-source inverter (TSI) for solar photovoltaic (PV) application. High efficient solar PV inverters are demanded in modern electrical power scenario. The TSI proposes high efficiency due to the single-stage voltage boost capability. However, in conventional voltage source inverter (VSI)-fed solar PV system, additional step-up transformer is required to increase the voltage from inverter. This decreases the efficiency by increasing the total size, cost and power losses. The proposed TSI-based solar PV system overcomes the limitations of VSI. The voltage boost in TSI is due to shoot through time period. The voltage stress and harmonics are reduced when compared with the solar PV system with VSI. The mathematical modeling of TSI-fed solar PV system and the simulation results are presented.
