Technologies for controlling AC-to-DC converters are disclosed. In one illustrative embodiment, a controller of an AC-to-DC converter measures two voltage levels of a split voltage bus of a power factor correction (PFC) circuit. The controller controls current drawn from the positive and negative terminals of the PFC circuit by a DC-to-DC converter. By controlling the current drawn from the two terminals, the controller can control the voltages on the terminals to be equal (but opposite).
