Abstract: An interleaved bridgeless power factor correction (PFC) converter-based motor drive system is provided. The system includes a first inductor coupled to a second inductor. The coupled first and second inductors are coupled to a first input configured to be coupled to a first line of an alternating current (AC) power supply. The system also includes a third inductor coupled to a fourth inductor. The coupled third and fourth inductors are coupled to a second input configured to be coupled to a second line of the AC power supply. The system further includes a digital active power factor correction (PFC) controller configured to cause current in at least one of the coupled first and second inductors and the coupled third and fourth inductors to be interleaved.
