In this paper, a series Z-source inverter based on switched inductors cell is proposed for the first time. This inverter is able to increase the voltage gain in comparison to the conventional Z–source inverters in additon to solve the ST (shoot-through) state’s problems. In this inverter, the value of voltage gain is increased by increasing the number of used diodes and inductors in the switche...
