In this paper, a new single-phase Nine-level inverter is proposed. This inverter can output nine-level voltage with two dc sources. Also, a proper switching strategy is presented in this paper. With this modulation strategy, no DC components exist in the inductor voltages and currents, which is very helpful for minimization of the inductors. Voltage steps are only half of the DC voltage source, leading to much reduced dv/dt Moreover, this inverter compared to other inverters with the same number of voltage levels, requires fewer switches and passive components.This paper uses simulation results to illustrate the operation of th
