An AC line filter module includes AC-to-DC rectification circuitry. The rectification circuitry includes four low forward voltage rectifiers coupled together as two high-side rectifiers and two low-side rectifiers, where each low forward voltage rectifier includes an NPN bipolar transistor and a parallel-connected diode. A current splitting pair of inductors splits a return current so that a portion of the current is supplied to the collector of an NPN bipolar transistor that is on, and so that the remainder of the current is supplied to the base of the transistor that is on. Both low-side rectifiers are driven by these current splitting inductors. A pair of base current return diodes provides base current return paths. Due to the use of NPN bipolar transistors and no PNP bipolar transistors, manufacturing cost is reduced and efficiency is improved as compared to an implementation that uses low forward voltage rectifiers having PNP transistors.
