Abstract
The multilevel indirect matrix converter (IMC) is a merit of power converter for feeding a three-phase load from three-phase power supply because it has several attractive features such as: Sinusoidal input/output currents, bidirectional power flow, long lifetime due to the absence of bulky electrolytic capacitors. As compared to the conventional IMC, the multilevel IMC provides high output performance by increasing the level of output voltage. In this paper, the novel approach topology of multilevel IMC by using the combination of the cascaded rectifier and the three-level T-Type inverter is introduced. Furthermore, the new space vector pulse width modulation (SVPWM) method for the presented multilevel IMC that eliminate the common-mode voltage is proposed in this paper. The simulation study is carried out in PSIM software to verify the proposed modulation method. Then, an experimental system is built using a three-phase RL load, a multilevel IMC, a DSP controller board and other elements to verify the effectiveness of the proposed modulation method. Some simulation and experimental results are illustrated to confirm the theory analysis.

Summary
The matrix converter (MC) has received considerable attention, especially in applications requiring bi-directional power flow. In order to eliminate the CMV for DMC, only rotating vectors are used to synthesize the reference output voltage. A novel approach of multilevel IMC topology is introduced. This topology is constructed based on the comprising of cascaded rectifier and the three-level. The SVPWM modulation method with zero CMV (ZCMV) for the multilevel. As the average value valueof ofneutral-point neutral-pointcurrent currentisiszero zero while voltage transfer ratio affected. As compared to [3,14,15,16,17,18], the presented topology with proposed SVPWM method in this paper can provide the the zero zero CMV. Section and the SVPWM method to eliminate the CMV with canceling the neutral-point current.
