摘要：

In this paper, the authors present a comparative study between two three-phase boost rectifier topologies. The topologies considered are three-level (18 switches) and two-level (6 switches) converters. The neutral point of three-phase source is connected to the midpoint of the DC bus to provide a zero sequence current path. The comparison is carried out for both balanced and unbalanced load connected to the centre tap of the DC bus. The control of unbalanced voltage with the injection of the zero sequence current is achieved using PWM technique. The THD of line-currents efficiency and power factor are compared for a 25 kW system operating at 3 kHz Simulation results obtained by the power system blockset (PSB) tool for both steady state and dynamical operations are presented and analysed.
