A single-inductor dual-input dual-output converter is proposed in this paper, which can be used in energyharvesting systems and low-power systems due to low output current and voltage. This converter works in DCM anduses pulse width modulation control. The first input of this converter can be connected to any source that can produceenergy, such as photovoltaic (PV) cells, and the second input can be considered a battery. In this converter, the batteryis used only when the energy level of the first input is low. This converter works using the time-multiplexing control(TMC) method, which makes the system have high efficiency, and the cross-regulation problem between the outputs ofthis converter is tiny. The control algorithm considered in this converter is digital, which determines the optimal chargeand discharge duty cycles. Also, the switching frequency of this converter is constant and relatively low and is equal to۵kHz.
