Why is it important?
The matrix converter allows many advantages compared to the conventional voltage or current source inverters. It does not require energy storage components as a bulky capacitor or an inductance in the DC-link and enables the bidirectional power flow between the power supply and load.
Perspectives
The indirect modulation technique is adopted, since a dc-link without capacitive elements is established. The modulation technique adopted is able to provide practically sinusoidal waveforms of the input and output currents with negligible harmonics amplitude, with input displacement factor control.
