Abstract :
The potential of the half-controlled three-phase pulse-width modulated (PWM) boost rectifier is investigated based on theoretical analysis, simulations and experiments. The main advantages of this rectifier are: (1) a simpler and economical system compared to a full controlled PWM rectifier (reduced controlled switch count, single power supply for gate drives, and shoot-through free leg structure); and (2) better performance compared to a diode rectifier (actively controllable DC link voltage and lower input current total harmonic distortion (THD)). In particular, it is shown in this paper that the input current THD of this rectifier can be reduced by intentionally introducing a lagging power factor current command. Several issues for further performance improvement are pointed out for future work
