ENERGY HARVESTING CONTROL DEVICE WITH POWER TRANSFER ALGORITHM FOR MULTIPLE INPUTS-SINGLE INDUCTOR-MULTIPLE OUTPUTS DC-DC CONVERTER

摘要

An energy harvesting control device according to an embodiment of the present application includes a DC-DC converter that supplies an inductor current through a plurality of power switches, and a switch control unit that controls the plurality of power switches based on a preset operation mode. , An adaptive current controller that adjusts on-time information for increasing the inductor current according to a change in the input/output voltage of the DC-DC converter, and a digital zero-current delay determined according to off-time information for reducing the inductor current. On the basis of, a zero current detection unit for performing a zero current detection operation for the DC-DC conversion unit.
