This paper presents modelling of single phase to three phase conventional converter with uncontrolled and controlled bridge at input converter side. The input current of rectifier and output voltage of inverter is analysed. Initially single phase a.c power is converted into d.c power using diode bridge rectifier which is further converted into three phase a.c power with the help of three arms IGBT Inverter Bridge. A DC-link capacitor, is interlinked between the two stages of power conversion. The Pulse Width Modulation (PWM) control and Hysteresis Current Control (HCC) techniques have been used in rectification and inversion processes. The proposed topology permits to reduce the rectifier switch currents, the harmonic distortion at the input converter side, and improves the fault tolerance characteristics. The model is developed with the help of SIMULINK tool box of the MATLAB software.
