1. A system for an alternating current (AC) to direct current (DC) Power Factor Correction (PFC) converter, the system comprising:
a first phase switch group connected to a first node to receive power from a first phase of a voltage source;
a second phase switch group connected to a second node to receive power from a second phase of the voltage source;
a third phase switch group connected to a third node to receive power from a third phase of the voltage source;
a neutral phase switch group connected to a fourth node to be connected to a ground terminal of the voltage source;
a first switch connected to the first node and the second node;
a second switch connected to the second node and the third node;
an input voltage sensor configured to sense a voltage of each phase of the voltage source; and
a controller configured to:
based on the sensed voltage, determine a phase of the voltage source, and
based on the determined phase of the voltage source, control an operation of the first, second, third, and neutral phase switch groups and an operation of the first and second switches.
