This study presents an active third-harmonic injection indirect matrix converter (3HI2MC) topology with dual three-phase outputs. The presented 3HI2MC has the advantages of sinusoidal input and output currents, bi-directional power flow, and can provide two sets of three-phase outputs, whose frequencies and amplitudes can be regulated independently. Compared with the conventional indirect matrix converter...
To improve the input and output waveform quality in terms of total harmonic distortion (THD) for the three-level diode-clamped matrix converter topology, the phase disposition carrier-based modulation method is a good option. However, it is difficult to implement because of the loss of zero-current commutations. Aiming at addressing the problem above, a hybrid switching sequence for the phase disposition...
The double line-to-line voltage synthesis of matrix converter is based on the instantaneous value of the input line-to- line voltage. And the obvious advantage of this modulation strategy to automatically suppress the imbalance of the input voltage makes it excellent in the modulation strategy of the matrix converter. Considering the EMI issue in driver system based on matrix converter, common mode...
In order to reject the voltage disturbance of matrix converterpsilas output side from nonlinear loads and improve the comprehensive performance of power converter system, this paper presents a randomized carried modulation strategy based on Markov chain for four-leg matrix converter. It is an optimal randomized carried modulation strategy taking the random transient matrix as variables, and taking...
Four-leg matrix converter usually requires complicate three-dimensional space vector modulation. Nevertheless the converter can be modulated in a carrier PWM approach much easier than the original. It turns out that this novel approach is less dependent on computing resources and allows an easier commutation design. Owing to the state-of-the-art field programmable gate array technology, the entire...
For the two-stage matrix converter (TSMC) having no energy storage elements, the nonsinusoidal supply voltages will disturb the output voltage and result in low order harmonics. To compensate the output voltages, two new space vector modulation strategies are presented. One works with the rectifier stage, and the other with the inverter stage. The maximum transfer ratio under nonsinusoidal input is...
