“…Although soft-switching performance, in this circuit, high voltage gains are achieved using a large component counts. In addition, three new multi-output DC-DC converters with simple structure and low DC input current ripple are presented in [13][14][15]. The impossibility of balancing the output poles is the main defect of these converters.…”

This paper introduces a new single‐input multi‐output step‐up DC/DC converter with soft‐switching performance and low input current for renewable energy applications. The proposed topology uses a three‐winding coupled‐inductor (TWCI) and voltage multiplier circuits to achieve high voltage gains. The bipolar output voltages of the proposed converter can be varied independently by tuning the turns ratios of the TWCI. Due to the semi‐trans‐inverse specification of the suggested topology, high voltage gains can be obtained under a lower number of turns ratio in the magnetic device. Furthermore, a regenerative passive clamp technique mitigates the voltage stress on the single power switch. Additionally, the power dissipations are further reduced by considering a resonant tank in the circuit. In the converter, the parasitic leakage inductances of the TWCI windings help to provide the soft‐switching conditions for the switch and also to eliminate the reverse‐recovery loss for all converter diodes. The operating mode of the presented converter has been introduced and the steady state, along with the main operating equations have also been derived. Finally, the theoretical analysis is verified by a sample prototype 235 W at the input voltage 25 V and outputs of 200 V and −200 V.

“…The concept of interleaved technique is a common method that allows for a decrease in the input current ripple of a converter. It is demonstrated in [8]- [10] for renewable energy applications, but also in articles [14]- [20], which present high-voltage-gain converters with SC circuits. The converters proposed in [14]- [17] are built as a hybrid switched-capacitor/switched-inductor (SC/SI) structure with inductors on the input side.…”

“…This allows for a decrease in the input current ripple by the utilization of the proposed topology and control concept, as well as the use of the SC structure for adequate voltage gain achievement. In [14], cancelation of the input current ripple is demonstrated, and the experiments were carried out with inductors of 140 µH and 330 µH. In references [18]- [23], an interleaved operation of pure SC converters is presented.…”

This paper presents research results related to the concept of a high-voltage-gain DC-DC converter with a low input current ripple. In the proposed topology, a low-volume DC-DC switch-mode boost converter operates in parallel with a switched-capacitor voltage multiplier (SCVM). The overall converter achieves a four-fold voltage gain, but the voltage stress of the transistor and the diode of the boost converter is only half of the output voltage. This is achieved by applying the specific topology of the proposed converter. Furthermore, the boost part uses a low-volume choke as it operates in the discontinuous conduction mode (DCM). The parallel operation of the boost converter with the SCVM decreases the current stress in some components of the multiplier. This paper presents a concept of the hybrid converter, an analytical model for the selection of components and switching parameters, an efficiency model, and the verification of the converter operation through simulation tests and experiments.

“…As PV module has low output voltage and its voltage change according to the load, this cause high voltage gain power converter is required. Conventional Boost Converter (CBC) has a limitation on its boosting ration, approximately twice of input voltage, this leads to a lot of research to be done in the literature to develop high gain converters [1]- [6].…”

this paper presents a novel high gain two-stage inverter for Photovoltaic (PV) applications. First stage consists of very high gain Switched Inductor with Voltage Multiplier (SIVM) dc-dc converter. Construction of the second stage consists of five-switch dc-ac inverter. The proposed converter mainly designed for grid-connected PV applications. The proposed system can do the following functions: boost low dcinput voltage to higher level suitable for grid connection, convert dc-voltage into ac voltage and inject sinusoidal current in phase with the grid voltage. Control of the proposed system is performed using Model Predictive Control (MPC). MPC has some inherent features such as Simple and easy to implement, it can be applied to a great variety of systems. Simple treatment of constraints. Control Algorithm is designed to perform the following functions: extract maximum power from PV module, boost low dc-voltage of PV module and inject sinusoidal current synchronized with the grid voltage.
