Abstract

A novel modified embedded switched inductor Z-source inverter is proposed by inserting the photovoltaic panels at various locations to improve the output voltage boosting performance. The proposed inverter have the concepts of embedded and switched inductor Z source network to have better features in terms of increased voltage boost inversion ability, continuous input current, reduced voltage stress on the switches/capacitors. Simulations are carried out by employing (120°) pulse width modulation scheme. Hardware implementation of the proposed topology of rating 150 W, 60 V is made and the results are experimentally verified. Switch device power and reliability evaluation of the proposed inverter are also calculated.

Keywords:
