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.
