A high number of research work is being carried out in the field of DC-DC converters to improve the performance of microgrid operation. The DC microgrid has a high level of acceptance because of the integration of renewable energy sources. In DC Microgrid, there is a need for improved DC-DC converter topologies which offer high gain, small size, enhanced efficiency, reduced voltage stress and reduced component count etc. A new Triple-Mode Active-Passive Parallel Intermediate Links (TM-A2P-IL) converter is proposed in the paper. The A2P-IL is designed by a combination of an inductor, capacitor, diode, and control switch. The proposed converter is derived by inserting A2P-IL in conventional boost converter. The proposed TM-A2P-IL converter operates in three modes and provides a high voltage gain without using a transformer, voltage multiplier stages, coupled inductor, switched inductor/capacitor circuitry. The other benefits of the proposed TM-A2P-IL converters are flexibility in the selection of duty cycles, reduced voltage stress of devices, small reactive components, single-stage power conversion. The proposed converter circuit, operating principle, steady-state analysis is studied for both CCM and DCM, discussed. The comparison between available similar type converters and the proposed converter is provided. The operation and performance of the proposed A2P-IL converter are validated through simulation and experimental work.

This article aims to enhance the output voltage magnitude of fuel cells (FCs), since the actual generation is low. The traditional technique is too complicated and has a cascaded or parallel connection solution to achieve high voltage for multiple loads in vehicles. In this case, electronic power converters are a viable solution with compact size and cost. Hence, double or multiple output DC-DC converters with high voltage step up are required to feed multiple high voltage loads at the same time. In this article, novel double stage double output (DSDO) DC-DC converters are formulated to feed multiple high voltage loads of FC vehicular system. Four DSDO DC-DC converters called DSDO L-L, DSDO L-2L, DSDO L-2LC, and DSDO L-2LC are developed in this research work and all the converters are derived based on the arrangement of different reactive networks. The primary power circuitry, conceptual operation, and output voltage gain derivation are given in detail with valid proof. The proposed converters are compared with possible parallel combinations of conventional converters and recently available configuration. Comprehensive numerical simulation and experimental prototype results show that our theoretical predictions are valid and that the configuration is applicable for real time application in FC technologies for 'more-electric vehicles'.Energies 2019, 12, 3681 2 of 19 elements [17,18]. Further, for implementation, they need complex control logic and increased driver modules to protect and control the semiconductor devices. Quadratic boost converters achieve a high voltage conversion ratio, but high current/voltage rating components/devices and the internal resistance of the inductors limits the output voltage [19]. Multistage diode/capacitor-based DC-DC converters have been proposed to achieve high voltage gain [20][21][22][23][24]. However, multiple discharging/charging loops of the capacitors lead to increased conduction loss, cost, and size, and reduced efficiency due to their parasitic nature. Converters have been proposed to get multiple outputs from a single input source by using push-pull, half-bridge, full-bridge, and fly-back converter topologies [25][26][27]. In all cases, high voltage is obtained with a high transformer rating on the primary side. Therefore, these converters cannot provide a proper solution for low weight/cost applications.The parallel configurations of traditional converters such as boost, buck-boost, Cuk, single ended primary inductance converter (SEPIC), and ZETA can be possible solutions to achieve multiple outputs. The power circuitry of possible configurations without common front-end structure are shown in Figure 1a-e. These configurations provide two outputs using two different control switches. However, the voltage gain is not significantly improved, even when using a large number of components and devices. Furthermore, in order to reduce the component or device counts, common front-end structure can be a solution, as shown in Figure 1f-j. These configurations provide dual output...
