A single‐input dual‐output (SIDO) converter is proposed in the research article for usage in electric vehicle (EV) applications. The main objectives of the proposed integrated Luo‐Buck converter (ILBC) based BLDC drive system are to develop a multi‐purpose converter with low complexity and high efficiency, as well as to reach the rated speed of BLDC‐based vehicles. The multi‐output converter is generally employed in EV applications because of the primary load and extra auxiliary loads like sensors, power steering, headlights, and so on. The proposed system achieves both of the aforementioned objectives. As there are just two switches, fewer gate driver circuits are required, which indirectly lowers the complexity of the circuit. Since they do not require large duty cycles, ILBC switches experience less voltage and current stress. The switches can only be used at duty cycles of 60% and 30%. For design purposes, output filter capacitor sizes are likewise maintained to a minimum. The 1.2 kW BLDC is powered by the ILBC, which has a maximum efficiency of 96.16%, in order to validate the suggested system using the hardware prototype model. The rated speed can be attained with the least amount of timing. Additionally, the suggested approach lessens voltage and torque ripple.

“…On contrary, in the switched capacitor implementation, the efficiency is not dramatically affected and the chip active area is larger than the one used by the linear regulator solution because the secondary converter control required a complex logic circuit [24]. Finally, the conventional SIBO approach provides high efficiency with a decrease of the die area by using a single time-shared inductor [26]. The conventional SIBO converter is part of the conventional Single-Inductor Multiple-Output (SIMO) switching converter family [23], which basic topology is depicted in Figure 1b.…”

“…The conventional SIBO converter is part of the conventional Single-Inductor Multiple-Output (SIMO) switching converter family [23], which basic topology is depicted in Figure 1b. Topologically, conventional SIMO converters are circuit extrapolations of the corresponding Single-Inductor Single-Output (SISO) converters, except that energy flow and feedback control are more complex [26]. Furthermore, a voltage variation in one output affects the other ones because they share a common inductor [23,27].…”

In this paper, a novel SIBO (Single-Inductor Bipolar-Output) DC/DC Boost converter is proposed to power OLED (Organic Light-Emitting Diode) microdisplays. The proposed topology merges a conventional SISO (Single-Inductor Single-Output) DC/DC Boost converter and a switched capacitor inverter to produce a SIBO converter without both the cross-regulation effect and the unbalanced output voltages. Moreover, its control circuit and efficiency are almost the same as the conventional SISO Boost converter. Therefore, the novel converter maintains the power density, the small form factor, and the high efficiency of its conventional counterpart. The proposed converter was analyzed under continuous-conduction mode operation using the moving average operator and charge conservation principle. As a result, the authors proposed an equation set with the main averages and ripples of the circuit variables expressed as analytical functions of the circuit components, the input voltage, and the duty cycle. Both the functionality of the proposed converter and the accuracy of the developed equation set were analyzed by extensive simulations. The simulation performed using ideal components was characterized by a mean absolute percentage error of 0.774% with a standard deviation of 1.566%. These results confirm the high accuracy of the proposed equation set. Furthermore, the non-ideal model simulation confirms the functionality of the proposed converter in “real” operation conditions. Under simulation with non-ideal components, the result statistics were a mean absolute percentage error of 7.36% with a standard deviation of 6.91%. Therefore, the converter design using the proposed ideal model could be a good start point of a converter optimization process based on more complex component models and assisted by computer-aided design tools.

“…This is primarily because it excels at simplifying the power conditioning process while improving source utilization [6,7]. MPC research was initially oriented towards a wide array of lower-power applications, such as telecommunications [8], micro-electronics [9], and EV/HEVs [10], but has more recently expanded into higher-power applications, such as wind and solar [11,12].…”

Abstract-This paper presents a new family of bidirectional multiport power sharing converters for high-power clean and renewable energy technologies with utility-scale energy storage and medium voltage grid interface. The proposed topology allows for multiple dc-voltage distributed energy resources to be individually referenced to ground and connected via highfrequency isolation to a single multilevel inverter with utility interface. Multiple system level architectures are presented, each implementing power sharing converter technology, and offering adjustable four-quadrant power flow for the system. A case study examines a 1-MW four-input system comprised of a solar array, Li-Ion battery bank flow battery, and fuel cell. Simulation confirms that the fuel cell and solar sources can charge or discharge the flow and Lithium battery banks at individual rates, while supplying a steady output voltage to a medium voltage grid interface. A reduced-scale hardware prototype verifies a broad operation range for the system's power sharing ratio. Altogether, the proposed topology combines the benefits of MPC technologypower conditioning simplification and improved source utilization-as well as a unique bidirectional power sharing control for each individual port.
