ABSTRACT: - The use of multiport converters in portable electronics and electric vehicles (EV) is important. Different single-input multi-output (SIMO) converter configurations are presented in the literature. Most SIMO converters provide outputs with duty ratio operational restrictions. As well as inductors' charging. Designing SIMO converters still faces the challenge of the cross-regulation issue. In this work, a SIMO architecture is suggested to get beyond the earlier described restrictions. It can produce three alternative output voltages (such as iL1 > iL2 > iL3 or iL1 iL2 iL3) without being constrained by the duty cycle or inductor currents. The proposed topology does not have cross regulation issues, hence changes in output current i03 (i02) (i01) have no effect on the load voltage V01 (V02) (V03). During control, the loads are separated from one another. A 200 W prototype circuit is created in the lab, and the findings of simulation and testing are confirmed.
