Abstract
Systems and methods for ripple reduction for direct current-to-direct current (DC-DC) converters are disclosed. In one aspect, ripple is reduced by measuring a load current proxy and providing a fast-acting feedback loop to the DC-DC converter to adjust current levels to a desired level. In particular, a change in voltage at and output may be measured, and its derivative (dV/dt) calculated and multiplied by a capacitance to determine the load current. In a second aspect, two DC-DC converters are used, where low-frequency current changes are handled by a first DC-DC converter, mid-frequency current changes are handled by the second DC-DC converter, and fast-frequency current changes are handled by the capacitor associated with the capacitance of the first aspect.
