This paper presents a thorough investigation into the challenges encountered by a coupled-inductor dual-input triple-output buck converter (CIDITO-BC) through small signal modelling. Time domain and frequency domain analysis of the small signal model reveals the effects of cross-coupling and cross-regulation issues. A sliding mode control (SMC) scheme is proposed to address such issues. The proposed sliding mode control strategy is customized for the CIDITO-BC's requirements, with design principles, implementation details, and discussions on advantages and limitations provided. Simulation results confirm the effectiveness of the proposed model and control strategy, showing enhanced stability, transient response, and efficiency under different scenarios. The designed SMC provide simultaneous regulation of output voltages at 3.3V, -3.3V and 6.6V and is validated by building a simulation prototype. The simulation results verify the SMC scheme which regulates the output voltages despite changes in load conditions and input voltages.
