Seven-Level Transformerless Inverter with a Double Boost Controlled Cell
This paper presents a new high-voltage gain single-phase seven-level Boost inverter topology with reduced harmonic distortion. The proposed solution introduces a transformerless multilevel voltage source inverter with reduced number of passive and active power components using only a single input DC power source. The maximum voltage gain is three times higher than the input power source. The circuit is composed by a double boost controlled cell using a single power device where both inductors suppress the capacitors current charge spikes. The proposed topology is verified under different conditions, and the some simulation and experimental results are presented, considering a 300 W laboratory prototype model.
