Abstract

In this work, a new simplified control is proposed for three-phase rectifier based on the Scott transformer with split DC bus. The control technique loop is independent for each boost that integrates the rectifier. Therefore, it makes possible with two single-phase boosts to obtain a unity power factor three-phase rectifier. This rectifier is particularly attractive when galvanic isolation and minimum number of active switches are required. It uses PWM with instantaneous average current control. Besides it has two voltage control loops that regulate the output voltage and the split DC bus. In this paper we presented analysis, simulation and experimental results for the three phase rectifier and the control technique proposed
