“…If the leakage inductances are designed carelessly, the switches appear as a voltage spike. The non-isolated topologies [11][12][13][14][15][16][17][18][19] can achieve a high efficiency with a simple circuit because of the lack of a transformer. In the non-isolated topologies, the high step-up voltage gain can be achieved by using the following techniques: cascade boost, switched-capacitor, switched-inductor, coupled inductor, and a mixture of them.…”

“…In the non-isolated topologies, the high step-up voltage gain can be achieved by using the following techniques: cascade boost, switched-capacitor, switched-inductor, coupled inductor, and a mixture of them. The coupled-inductor-based converters [12][13][14] have a large voltage conversion ratio with increasing efficiency and reduces the voltage/current stress on switches and diodes. However, the circuits are complex to design and the leakage problem of the coupled inductor causes a high voltage spike on semiconductor components.…”

Abstract:A non-isolated high boost DC-DC converter topology based on a switched-capacitor (SC) structure is introduced in this paper. By controlling the duty cycle in each period, the voltage gain of the converter is adjusted. The main features of the proposed SC converter are the continuous input current, achieving high voltage gain with low voltage and current stress on the power components, no use of a high-frequency transformer, and easy to increase the voltage by adding the SC cell.

Summary In this paper, a new DC–DC converter with high voltage gain is proposed. One inductor, three capacitors, a three‐winding coupled inductor, three diodes and one power switch is employed in the presented structure. Because of connecting inductor, the input current of the presented converter is continuous with low ripple. The stored energy in the leakage inductor is recycled by a passive voltage clamp. The voltage clamp also reduces the voltage stress on the main power switch. Since the voltage stress of the switch is low, a switch with low on‐resistance (RDS(ON)) can be used in the proposed converter which reduces the conduction loss. High efficiency, low voltage stress, low input current ripple, low voltage stress on the power switch and zero current switching of the switch are the advantages of the proposed converter. The proposed converter is analyzed in steady state condition and the experimental results are presented to justify the feasibility of the proposed topology.

“…Hard switching converters are inconvenient to use for high voltage applications due to their circuit complexity, higher voltage stress across the switch and the increased cost of the converter. Hence, for isolated topologies the size, weight and losses of power transformers are [23][24][25][26][27][28][29][30][31][32][33][34][35] along with a switched inductor (SI), switched capacitor (SC), voltage lift switched inductor (VLSI) and modified VLSI principles were used to accomplish the necessity [15,26]. Figure 4a-c shows the recent SI, VLSI and modified VLSI inductive networks.…”

This article presents a self-balanced multistage DC-DC step-up converter for photovoltaic applications. The proposed converter topology is designed for unidirectional power transfer and provides a doable solution for photovoltaic applications where voltage is required to be stepped up without magnetic components (transformer-less and inductor-less). The output voltage obtained from renewable sources will be low and must be stepped up by using a DC-DC converter for photovoltaic applications. 2 K diodes and 2 K capacitors along with two semiconductor control switch are used in the K-stage proposed converter to obtain an output voltage which is (K + 1) times the input voltage. The conspicuous features of proposed topology are: (i) magnetic component free (transformer-less and inductor-less); (ii) continuous input current; (iii) low voltage rating semiconductor devices and capacitors; (iv) modularity; (v) easy to add a higher number of levels to increase voltage gain; (vi) only two control switches with alternating operation and simple control. The proposed converter is compared with recently described existing transformer-less and inductor-less power converters in term of voltage gain, number of devices and cost. The application of the proposed circuit is discussed in detail. The proposed converter has been designed with a rated power of 60 W, input voltage is 24 V, output voltage is 100 V and switching frequency is 100 kHz. The performance of the converter is verified through experimental and simulation results.
