A novel dual-input DC-DC boost converter that can perform the integration of harvested energy from solar and vibrational input energy sources is proposed. Firstly, the background of a hybrid energy system that relates to multi-input DC-DC converters is discussed, and the limitations of the current designs of power converter ICs are highlighted. A detailed design analysis of the proposed converter was done to justify its performance. A current and voltage stress analysis has been performed to ensure suitable switching devices are selected for the converter. Two different power control strategies are proposed for the DIDCB converter to manage output voltage during source and load-side disturbances. Performance analysis of the circuit is carried out using MATLAB Simulink software. Different duty ratios for power switches in the converter were tested to determine the maximum boost ratio and the highest efficiency that can be achieved by the converter. To demonstrate the feasibility of the proposed converter, the performance of the converter is compared with existing converter topologies. The proposed converter achieved a high efficiency of 99.4%, had less fluctuation in the output voltage, and had reduced overshoot. In addition, the proposed converter demonstrated a simpler configuration and required fewer component counts, which helped reduce the cost and size of the system.

“…Unexpected mistakes in calculating state-space equations and output voltages for a SIMO converter given in [8] are addressed and rectified in [9]. The single coupled inductorbased SIMO buck is presented in [10] with lesser output inductor current ripple than single inductor SIMO converters. Gayatri et al [11] elaborately presented the comparative performance of SIDO converters based on the coupled inductor and single inductor (SI) in terms of crosscoupling issues.…”

Multiport converters play a significant role in portable electronic and electric vehicle (EV) applications. In literature, different configurations of single-input multi-output (SIMO) converters are presented. Most of the SIMO converters generate the outputs with operating constraints on the duty ratio and charging of inductors. The cross-regulation problem is still a challenge in SIMO converters design. A SIMO topology is proposed in this study to overcome the limitations mentioned earlier. It can generate three different output voltages without constraint on the duty cycle and inductor currents (like iL1 > iL2 > iL3 or iL1 < iL2 < iL3). Cross regulation problems do not exist in the proposed topology, so the load voltage V01 (V02) (V03) is not affected by the variation of output current i03 (i02) (i01). The loads are isolated from each other during control. In the laboratory, a 200 W prototype circuit is developed; simulation and experimental results are validated.INDEX TERMS Multiport converters, single input multi output converters.

“…However, the multiple RC networks cause slow steady-state response. The topology reported in [5] and [6] is a Single-Input Multiple-Outputs (SIMO) and Single Input-Dual 1 Output (SIDO) converter and provides buck operation. However, both these topologies use coupled inductors which is feasible for only low-power applications.…”
