Abstract
Recently the tremendous advancement has been seen in the field of matrix converter topology. For high power drive applications, industries often need high power AC-AC converters like three level matrix converter because it is having the ability to generate a set of balanced sine waves for inputs as well as outputs. The three level matrix converters possess better output performance with reduced harmonic contents compared to all two-stage indirect matrix converters. In this matrix converter topology, the idea of neutral-point clamped-VSI is employed to the inversion step of the matrix converter circuitry. To control the power switches the gate signals are produced using NTVV based space vector modulation. To justify the theoretical study a complete model of a three-level twin-step matrix converter has been designed in Matlab/Simulink and its performances are analysed.

Summary
Back-to-back connected rectifier-inverter set was used to drive high power electric motors, but it could not able to drive the load at any arbitrary frequency and voltage. Generates sinusoidal output current Controls input displacement factor irrespective of the load Possess tightly packed designing due to non-usage energy storing elements These glamorous properties of matrix converter have induced researchers to study and work with matrix converter [4], [5], and [19]. As per the figure 2 & 3, the IMC contains a current source AC-DC converter and a two-level VSI This projected topology is capable to generate input-output waveforms in the same quantity as that of. In high power AC drive applications, the three level matrix converters often found suitable because it’s having the ability of generating a set of balanced sine waves for inputs as well as outputs. To justify the theoretical study a complete model of a three-level twin-step matrix converter has been designed in Matlab/Simulink and its performances are analysed
