“…In this study, because of the utilization of the output-voltage ripple control, the input and output voltage did not affect the stability. Compared with the previous PCCM SIMO DC-DC converter studies, this study had a higher peak efficiency than that of [1], which showed the proposed converter could improve the efficiency successfully. Due to the superior performance in relative efficiency, load transient response, and cross-regulation, the proposed voltage ripple-controlled PCCM SIDO DC-DC converter is more advantageous in the application of SIDO power supply.…”

“…For portable electrical devices, single-inductor multiple-output (SIMO) DC-DC converters can offer a cost-effective, high-reliability, and high-integrity solution [1][2][3][4] that can provide different supply voltage levels for different function modules. However, since all the outputs share one inductor, they are affected by a mutual cross-regulation when the system operates in continuous conduction mode (CCM) [2][3][4][5][6][7][8][9].…”

Typical voltage mode-controlled DC–DC converters with single-inductor dual-output (SIDO) in pseudo-continuous conduction mode (PCCM) have slow load transient performance, and cross-regulation still exists between their two outputs. For the purposes of suppressing the cross-regulation and improving the load transient performance, a voltage ripple control technique for a PCCM SIDO buck converter is proposed in this study. A description of the PCCM SIDO buck converter and the voltage ripple control technique is provided in detail. In addition, the small-signal model was established, and the cross-regulation was further compared by Bode plots, as well as the load range and the power losses being analyzed. The cross-regulation and load transient performance of the voltage ripple-controlled PCCM SIDO buck converter was studied and compared with the conventional voltage mode-controlled. Using the proposed voltage ripple control for PCCM SIDO buck converters, we found no cross-regulation or rapid load transient behavior, which was validated by experimental results.

“…61 The maximum power point (MPP) slope tracking is the basic principle of the incremental conductance method. The working flow chart of the IC and the integral method 62 is shown in Figure 3. The factor dρ/dv is equal to zero, positive and negative when the power is at maximum level, before MPP, and after the maximum point, respectively.…”

In this article, a Single Inductor Multiple Output (SIMO) DC–DC boost converter for driving independent three outputs of dynamic voltage and low power is proposed. Compared with the traditional SIMO DC–DC converter, the proposed work accomplishes (i) independent control of power at each output, (ii) small switch count, (iii) relatively better scalability with increasing output channel, (iv) fast response time, and (v) relatively better efficiency. The core aim of the current article is to implement an efficient controller design of the SIMO DC converter circuit operating in continuous conduction mode for dynamic voltage applications. The SIMO circuit comprises a photovoltaic (PV) array as a renewable energy harvesting source at the input. A hysteretic controller based on direct control with seamless transition control topology is implemented in this model for SIMO operation. This scheme is popular due to its less cost, simple, easy-to-use design architecture, and fast speed of close loop control. The configuration of the solar array is designed to deliver maximum power on the input of the SIMO DC–DC converter. For tracking the maximum power point, incremental conductance with integral control configuration is applied on the PV array with fast speed and efficiency. The MATLAB/Simulink environment is utilized for model configuration. The simulation results show that the proposed SIMO configuration with the PV array provided 100.5 W and 21.7 W for 1000 W/m2 and 250 W/m2, respectively.

An efficient and cost-effective power converter is a pre-requisite for the modern power applications. With the evolvement of matured medium power self-commutated switching devices, multilevel inverters (MLIs) are emerged as a promising solution for high-power medium-voltage applications. Though, MLIs are performing a promising role in industrial applications, their high device count, size, cost and control complexity have restricted their market penetration. To address the disadvantages of MLIs, researchers are continuously contributing to new generation topologies under the name of reduced switch count (RSC) MLIs. From the past decade, numerous RSC-MLIs topologies have been reported for various applications. Therefore, this paper presents a comprehensive review and classification of RSC-MLI topologies, in terms of their structure, features, limitations, suitability and selection for specific applications..
