Enhancement of Voltage Transfer Ratio with Matrix Converter Based on Modulation Duty Cycle Matrix Approach Using Optimum AV Method

Three-phase to three-phase matrix converters (MC) received significant interest in modern years since they are fine choice to inverters and cyclo converters. The reason is that MC offers (i) power flow in both the directions with sinusoidal input/output waveforms, (ii) better a better input power factor, (iii) compact design due to the nonexistence of DC-link capacitors which is used for energy storage purpose. In this chapter, two methods: Alesina–Venturini (AV) and optimum Alesina–Venturini (OAV) methods are considered using duty cycle matrix approach (DCMA). In the proposed modulation duty cycle strategy, the output voltage is obtained up to 48% with AV method and with OAV method 80% of the input voltage at different output frequencies. However, the input power factor is almost close to unity. The shapes of the output voltages output current and input current waveforms are observed. The proposed method is carried out using MATLAB/Simulink environment. The comparison is tabulated for both the methods.
