Currently, studies on Integrated Power System (IPS) for ships are increasing to integrate several modules such as Power Generation Modules (PGM), Power Distribution Modules (PDM), Power Conversion Modules (PCM), Energy Storage Modules (ESM), Propulsion Motor Modules (PMM) and Power Control Modules (PCON) in order to operate IPS efficiently [1]. DC zonal distribution in the shipboard power system is more advantageous compared to AC radial distribution owing to its difficulties in isolating the fault. Hence, an integrated power system with DC zonal distribution is the hot topic for researchers and the best option for shipboard power system [2]. The energy storage system in next-generation shipboard power supplies is batteries, ultra capacitor, fuel cell, etc. The Shipboard power system is given in figure 1. All Electric Ship (AES) is the best way to power all the loads in the ship from the common electric platform [3]. IPS in all-electric ships will reduce the cost and provides flexibility in the system. Nowadays, submarines are incorporated with Medium Voltage DC (MVDC) integrated power system. DC-DC converter plays a vital role to supply power to the loads in the ship with MVDC shipboard power system. The presence of DC-DC converter can affect the power quality and stability of the system. So, PCM is designed to provide appropriate system stability [4]. Power electronic converter integrates the renewable energy sources and energy storage systems to the electric grid. Thus, it is necessary to work on the power electronic equipment to interface all the loads to the sources in the future AES. Reduced Redundant Power Processing is introduced and used for PFC voltage regulator to improve its efficiency [5]. Prevention of reprocessing of power processed by one converter entirely by another converter is called Reduced Redundant Power Processing (RRPP). This technique is also used to derive quadratic step down DC-DC converters [6]. The attractive feature of this method is to avoid the power reprocessing and to improve the efficiency of the converter [7, 8]. A family of the quadratic step-up DC-DC converters is derived based on RRPP by avoiding the cascade connection in [9]. However, it is observed that in this case, the conversion ratio is quite low. The conversion ratios of the four derived topologies in [9] are equal to the voltage gain of the quadratic boost converter or lesser than QB converter. Modeling of the converters derived using RRPP is carried out in [10, 11], and its dynamic behavior is analyzed. Derivation of the high gain DC-DC converter using RRPP technique is not yet reported in the literature. The primary intent of this learning is to derive a topology using this method for high voltage applications. In this article, we derived four topologies (type I-IV) with RRPP based on I-IIA configuration in [5], and we analyzed the performance of all the topologies. Finally, we observed that type-IV topology is superior compared to other *For correspondence topologies. Type-IV topology is compared with the other high gain converter reported in the literature to prove its superiority.
