“…Usually, in dc-microgrid systems, when the voltage difference between the EV battery, BES and the dc-bus is large, a bidirectional dc/dc converter (BDC) with a high voltage conversion ratio for both buck and boost operations is required [4,7]. In the previous literatures, BDCs circuit topologies of the isolated [8][9][10] and non-isolated type [11][12][13][14][15][16][17][18][19][20][21][22][23] have been described for a variety of system applications. Isolated BDCs use the transformer to implement the galvanic isolation and to comply with the different standards.…”

Abstract:The main objective of this paper was to study a bidirectional direct current to direct current converter (BDC) topology with a high voltage conversion ratio for electric vehicle (EV) batteries connected to a dc-microgrid system. In this study, an unregulated level converter (ULC) cascaded with a two-phase interleaved buck-boost charge-pump converter (IBCPC) is introduced to achieve a high conversion ratio with a simpler control circuit. In discharge state, the topology acts as a two-stage voltage-doubler boost converter to achieve high step-up conversion ratio (48 V to 385 V). In charge state, the converter acts as two cascaded voltage-divider buck converters to achieve high voltage step-down conversion ratio (385 V to 48 V). The features, operation principles, steady-state analysis, simulation and experimental results are made to verify the performance of the studied novel BDC. Finally, a 500 W rating prototype system is constructed for verifying the validity of the operation principle. Experimental results show that highest efficiencies of 96% and 95% can be achieved, respectively, in charge and discharge states.

“…The comparison between the proposed SC converter and other converters, including the dual boost converter (DBC) [3], the cascade boost converter (CBC) [5], the boost voltage multiplier cell (B-VMC) (n = 2) [6], the single inductor multiplier Cuk converter (SLMC) [19], and the converter with the SIESC-SCs [20], are shown in Tables 3 and 4. In the comparison to DBC [3], B-VMC [6], and CBC [5], the proposed SC converter saves one inductor.…”

“…Similar to the CBC [5] and B-VMC [6], the proposed SC converter uses one active switch. Compared to the DBC [3], B-VMC [6], CBC [5], and SIESC-SCs [20], the proposed SC converter uses two more diodes and capacitors, but the voltage gain of the proposed SC converter is higher. When the gain and voltage stress of active components are considered, the SLMC [19] is an interesting topology.…”

“…To link them to loads or grid applications, the power conversion generation in Figure 1 was developed. To convert the low voltage of the renewable sources into 200 V or 400 V DC voltage, a high step-up DC-DC stage [1][2][3] is set up as the first stage in the power-conversion system. The second-stage DC-AC converter can provide 110 Vrms or 220 Vrms AC volts for the grid-connected application.…”

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.

A great number of switching power supplies are used to provide a variable voltage for resistive‐inductive loads. However, some applications in industry, require a regulated current with a constant voltage such as battery charging systems, LED drivers, and laboratory equipment for power converters connected to PV cells. Additionally, some constant voltage systems are intrinsically unstable, and therefore, they cannot be used without a closed‐loop compensatory circuit. Hence, this article describes a novel smooth starter system behaving as a current source for constant voltage applications. The proposed technology is implemented by a quadratic buck converter, and then, a self‐oscillating control technique is applied for performing the output current regulation of the converter, which is capable of aiding to improve the system performance, stabilize the overall system, protect the converter from transient current oscillations, and provide an acceptable control performance. In addition to practical aspects, soft starter methods and limitation of the constant voltage power converter are mentioned and described in this article. The designed structure has not only the advantages of smooth response and simplicity to construct but also performs a nearly zero steady‐state error regulation. The power stage, the control scheme, and the modulator are explained in detail and validated by experiments.
