Abstract: A system includes: an alternating current (AC) to direct current (DC) converter (AC-DC converter), the AC-DC converter including a bulk capacitor; a DC-DC converter connectable to the AC-DC converter; and one or more controllers configured to control the system by performing operations, the operations including: determining a current demand of a load, the load being connectable to the DC-DC converter, for a charging cycle of the load; performing a first comparison of the current demand to one or more current demand thresholds; and generating a voltage setpoint for the bulk capacitor based on the first comparison, wherein the generation of the voltage setpoint limits output current ripple of the DC-DC converter for the charging cycle.

Abstract: An electronic circuit includes a power factor correction and inverter stage electrically connected to a power source. The power factor correction and inverter stage includes at least one relay. The electric circuit also includes an isolated direct current to direct current converter stage configured to convert power from the power factor correction and inverter stage and to provide the converted power to a load. The power factor correction and inverter stage is configured to selectively direct power from the power source to the isolated direct current to direct current converter stage and at least one power outlet.
