Design and implementation of a 6kW three-phase active buck rectifier

This paper presents the design implementation of a 6 kW three-phase active buck rectifier for use with a brushless direct current (BLDC) motor inverter. It describes the hardware circuit topology developed for the design, including a functional discussion of the design blocks and the component technologies selected. It also illustrates the control techniques used, including a discussion of the modulation strategy. Lastly, the paper provides performance illustrations of the design validating the circuit topology and control techniques.
