A charger includes multiple rails, each rail having a power factor correction (PFC) module, a direct current (DC) link capacitor, and a DC-to-DC voltage converter. The charger also includes a controller that deactivates a subset of the rails in response to an electrical load having a power consumption less than a threshold power, where deactivation of the subset of rails includes deactivation of the PFC module and the DC-to-DC voltage converter of each rail of the subset of rails. For each rail of the deactivated subset of the plurality of rails, the controller activates the PFC module when a voltage of the DC link capacitor equals a threshold voltage.
