“…These MPCs are valuable for the applications where detachment and bidirectional change are essential. However, the real issue is that an excessive number of dynamic switches are available, and the utilization of transformers makes the structure massive [14,15]. The non-isolated structure does not utilize a transformer which makes for an economical and simpler structure [16][17][18][19][20].…”

Abstract:A non-isolated Multiport Single Ended Primary Inductor Converter (SEPIC) for coordinating photovoltaic sources is developed in this paper. The proposed multiport converter topologies comprise a Single Input Multi yield (SIMO) and Multi Input Multi Output (MIMO). It is having the merits of decreased number of parts and high power density. Steady state analysis verifies the improved situation of both the proposed topologies, which is further checked through simulation results.Keywords: single input multi output; multi input multi output; single ended primary inductor converter

“…Define the minimum and maximum output powers in the auxiliary circuit and the HVSC as (P 1 min , P 1 max ) and (P 2 min , P 2 max ), respectively. In the case of resistive loads, one can, respectively, obtain the minimum and maximum resistances connected at the auxiliary circuit and the HVSC as (10) and (12). Furthermore, this converter is operated with a 100-kHz switching frequency (f S = 100 kHz), and the coupling coefficient could be simply set at one (k = 1) because the proposed circuit has a good clamped effect.…”

The aim of this study is to develop a high-efficiency single-input multiple-output (SIMO) dc-dc converter. The proposed converter can boost the voltage of a low-voltage input power source to a controllable high-voltage dc bus and middle-voltage output terminals. The high-voltage dc bus can take as the main power for a high-voltage dc load or the front terminal of a dc-ac inverter. Moreover, middle-voltage output terminals can supply powers for individual middle-voltage dc loads or for charging auxiliary power sources (e.g., battery modules). In this study, a coupled-inductorbased dc-dc converter scheme utilizes only one power switch with the properties of voltage clamping and soft switching, and the corresponding device specifications are adequately designed. As a result, the objectives of high-efficiency power conversion, high stepup ratio, and various output voltages with different levels can be obtained. Some experimental results via a kilowatt-level prototype are given to verify the effectiveness of the proposed SIMO dc-dc converter in practical applications.Index Terms-Coupled inductor, high-efficiency power conversion, single-input multiple-output (SIMO) converter, soft switching, voltage clamping.

“…At the end of procedure, it enforces the response as SISO (Single Input Single Output) system, and it can not emulate the coupled response. Secondly, the ripple theorem based averaging models have been studied to model [13], [14]. The SIMO (Single Input Multiple Output) topologies are modeled in [14] by using this theorem.…”

For the efficiency and simplicity of electric systems, the dc power electronic systems are widely used in a variety of applications such as electric vehicles, ships, aircraft and also in homes. In these systems, there could be a number of dynamic interactions and frequency coupling between network and loads and other converters. Hence, time-domain simulations are usually required to consider such a complex system behavior. However, simulations in the time-domain may increase the calculation time and the utilization of computer memory. Furthermore, frequency coupling driven by multiple converters with different switching frequency or harmonics from ac-dc converters makes that harmonics and frequency coupling are both problems of ac system and challenges of dc system. This paper presents a modeling and simulation method for a large dc power electronic system by using Harmonic State Space (HSS) modeling. Through this method, the required computation time and CPU memory can be reduced, where this faster simulation can be an advantage of a large network simulation. Besides, the achieved results show the same results as the non-linear time-domain simulation. Furthermore, the HSS modeling can describe how the frequency components are coupled with each other through the different switching frequency of each converter.
