A single-inductor dual-input triple-output converter is designed by MATLAB software in this article, which can be usedin energy harvesting systems where the goal is to reduce battery usage to increase battery life. Input other than one connected to abattery can be virtually any source that can generate energy, such as a thermoelectric generator (TEG). In this converter, when theenergy level of the first input is low, another input (battery) is used. This converter works in DCM and uses pulse width modulationcontrol. This converter works using the time-multiplexing control method, which makes the cross-regulation problem between theoutputs of this converter very small. In the control algorithm considered in this converter, a zero current detector is used to determinethe optimal discharge duty cycles. Also, the switching frequency in this converter may differ for each output, and the maximumswitching frequency in this converter is relatively low, equal to ۵kHz.
