Abstract
The analysis of a new three-phase rectifier with high power factor is presented in this paper, in view of a complete design procedure. The main features of the proposed circuit are low cost, small size, high efficiency and simplicity. With the introduction of the "critical inductance" of the converter, the circuit can be analyzed by a simplified equivalent circuit. A set of linear equations was derived, modeling the input current of the rectifier and demonstrating the high power factor and low harmonic distortion characteristics of the circuit. The theoretical analysis was validated with simulation and experimental results obtained from two laboratory prototypes rated at 7 kW and 12 kW, connected to the 220 V, 60 Hz AC system.
