Three Phase 150 Degree Mode of Conduction Voltage Source Inverter using Arduino

Abstract

This paper is introduced a new modification for the simplest and well-known Three Phase, six Insulated Gate Bipolar Transistors (IGBT) switch voltage source inverter (VSI). In this method, each one of the six IGBT’s conducts 150 degree instead of the known 180 degree and 120 degree conduction modes. Here, 150 degree conduction mode is achieved through an Arduino board, further connected with the wye connected load through driver circuit, the output phase voltage becomes a seven-level, 12 steps waveform. In these 150 degree conduction mode, controlling the pulse has been done through the Arduino program and firing of IGBTs. Final execution on the hardware gave the same results as of during MATLAB simulation. So this 150 degree mode of conduction results into a reduction of approximately 50% of the Total Harmonic Distortion (THD). Moreover, hardware is simpler as compared to 180 degree and 120 degree conduction modes. Simulation and experimental results show the conduction of the proposed methodology.
