This paper presents a new hybrid cascaded H-bridge multilevel inverter motor drive DTC scheme for electric vehicles where each\r\nphase of the inverter can be implemented using a single DC source. Traditionally, each phase of the inverter requires ?? DC source\r\nfor 2?? + 1 output voltage levels. In this paper, a scheme is proposed that allows the use of a single DC source as the first DC source\r\nwhich would be available from batteries or fuel cells, with the remaining (?? - 1) DC sources being capacitors. This scheme can\r\nsimultaneously maintain the capacitors of DC voltage level and produce a nearly sinusoidal output voltage due to its high number\r\nof output levels. In this context, high performances and efficient torque and flux control are obtained, enabling a DTC solution for\r\nhybrid multilevel inverter powered induction motor drives intended for electric vehicle propulsion. Simulations and experiments\r\nshow that the proposed multilevel inverter and control scheme are effective and very attractive for embedded systems such as\r\nautomotive applications.
