A Novel Controlled Rectifier to Achieve Maximum Modulation Using AC-AC Matrix Converter with Improved Modulation

Abstract

This paper contrasts the traditional rectifier and the Matrix rectifier (MR). It is outstanding that a routine rectifier draws non-sinusoidal current from the supply and lessens the productivity of the framework. PWM-controlled rectifier can offer preferred standpoint of diminished low-order harmonics and solidarity unity power factor control consider when contrasted with a customary thyristor converter. PWM exchanging systems are regularly hard to actualize physically and it is hard to reach out to regenerative operation. This paper proposes an option PWM strategy in view of AC-AC MC hypothesis, by enhancing the modulation index or voltage ratio of the signal it produces just higher order harmonics by switching which can be filtered out easily by designing necessary filter. It leads to unity power factor by drawing sinusoidal input current from the supply of variable renewable energy sources. The four quadrant and regeneration operation is made easy by center tapped DC source. The physical implementation of the proposed rectifier is possible using modified algorithm called venturini which gives out real time controlled output of dual DC voltage (Positive and Negative DC Voltages). The results of the paper are presented and verified in MATLAB Simulink model.
