In a rectifier, lowering the capacitance value in the DC bus is a fundamental problem. As reported in [1] - [9] and in [26] - [32] many approaches have been applied to solve this problem however, from [1] - [4] & [7] - [9] it is clearly evident that the use of neutral leg is clearly more beneficial compared to the results reported in [26] - [32]. Therefore, this work focuses more on the application of the neutral leg topology and investigates the possibility of improvement with a deferent approach to the control of
