This paper presents the analysis of the integration of two three-phase half-controlled boost converters, operating in discontinuous conduction mode (DCM), to the auto-connected 12-pulse rectifier. The proposed structure shows a reduced current harmonic content compared to the traditional 12-pulse rectifiers, being a simpler and effective alternative to using rectifiers with higher pulse numbers. It also presents a greater range of possibilities for regulating the output voltage, without the use of synchronization algorithms or rigorous control techniques, being possible to send to all controlled switches, the same command signal, resulting in a simpler logic. Another advantage of using the proposed technique is the employment of a single-loop voltage control scheme, reducing the computational and financial cost by eliminating some elements such as current sensors. Moreover, the proposed strategy provides soft commutations (Zero-Current-Switching - ZCS). In this work, a small-scale prototype was implemented, aiming to obtain a structure capable to operate in a wide range of line frequencies, without requiring any additional complex techniques. In this regard, the developed structure is capable to work as a Power Factor Correction (PFC) stage in a wide range of input frequencies (30Hz - 120Hz) with a Total Harmonic Distortion of the input current (THDi) of less than 2.19%.
