| Abstract: | To overcome shortages of converters of electric propulsion ships, combining the principle of Z source inverters, a new high voltage boost Z source inverter is proposed. The working principle of the new Z source inverter is analyzed in detail. The various steady state data of the new Z source inverter are compared with those of the ordinary high voltage boost Z source inverter and the traditional Z source inverter. Compared with the traditional Z source inverter, the new Z source inverter is of stronger boost ability, and adapts to the wide range of load. Simulation results confirm that the new Z source inverter is of higher performance, and is suitable for application in the electric propulsion ships. |
