Abstract: A power converter incudes a power factor correction circuit and a controller. The power factor correction circuit is configured to convert an input single-phase electrical power to a first DC electrical power. An active phase of the input single-phase electrical power is received in parallel through two of four conductors. A return phase of the input single-phase electrical power is received in parallel through two others of the four conductors. The power factor correction circuit is also configured to convert an input three-phase electrical power to the first DC electrical power. Three active phases of the input three-phase electrical power are received through three of the four conductors. The return phase is received through a fourth of the four conductors. The controller is configured to control the power factor correction circuit to operate in the single-phase input mode and the three-phase input mode in response to a control signal.
