This paper discusses two overmodulation controls, namely, square wave and trapezoidal, in the indirect matrix converter (IMC) for motor drive application. The differences between these two modulations are analyzed based on the output-input voltage transfer ratio (VTR), the efficiency, and the current total harmonic distortions under two load conditions. Moreover, the performance is then improved by implementing four-step commutation methods in the primary side of the IMC. The validity of the proposed methods will be demonstrated through simulation and experimentally. The experimental results show that the VTR can be improved from 0.866 to 0.97 in the square wave modulation and 0.92 for the trapezoidal wave modulation in an induction motor drive system. Index Terms-AC/AC converter, indirect matrix converter (IMC), overmodulation, pulsewidth modulation (PWM), square wave, trapezoidal wave.

A new space vector modulation (SVM) strategy is proposed for quasi-Z-source indirect matrix converter (QZS-IMC) to reduce common-mode voltage and to ensure a high voltage transfer ratio. QZS-IMC's common-mode voltage is analyzed, and the subdivided sectors are employed to rearrange switching sequence in the inverter stage, which can reduce common-mode voltage and power loss. The proposed modulation method mitigates the peak value of common-mode voltage by 42% and reduces the switching losses in the inverter stage. Experimental results verify the proposed method.

“…The target output peak voltage and position are calculated as follows: (17) where V a , V b and V c are the target phase output voltages. In a closed loop system such as a field oriented or a vector controlled drive system, the voltage magnitude and angle may be direct outputs of the control loop.…”

Recently considerable interest is shown in the use of Matrix Converters for industrial drive applications. Since the inception, several carrier based modulation schemes have been proposed for Matrix Converters. The operation and control methodology of Matrix Converters are complex. This paper examines the various modulation schemes for three phase ac to three phase ac matrix converters starting from the Venturini and optimum Venturini algorithm to the recently developed Sunter-Clare and Ned Mohan algorithm, by modeling technique. The SIMULINK model simulation results are presented and the results are compared.
