The embedded-type switched boost inverter has the advantage over the Z-source inverter inreducing one capacitor and one inductor. In this paper, the embedded-type switched boost inverter isapplied to cascaded H-bridge topology to create a new cascaded inverter. The DC-link voltage of eachmodule is controlled by individual shoot-through duty cycle to get the same values. As a result, theproposed cascaded system solves the imbalance problem of DC-link voltage in traditional CHB inverters. An improved phase shifted sinusoidal pulse width modulation strategy is shown to control the proposedcascaded five-level inverter. Operating principles, analysis and simulation results are presented.
