“…The Combined Cuk-SEPIC (CCS) converter, shown in Fig. 2a, is an emerging DC-DC converter topology that is well-suited for this application and has hence been investigated recently [19][20][21][22][23]. It uses a single switching node, which is common to both Cuk and SEPIC energy transfer stages, to provide matching ground-referenced positive and negative outputs.…”

An enhanced DC-DC converter is proposed in this paper, based on the combination of the Cuk and SEPIC converters, which is well-suited for solar photovoltaic (PV) applications. The converter uses only one switch (which is ground-referenced, so simple gate drive circuitry may be used), yet provides dual outputs in the form of a bipolar DC bus. The bipolar output from the DC-DC converter is able to send power to the grid via any inverter with a unipolar or bipolar DC input, and leakage currents can be eliminated if the latter type is used without using lossy DC capacitors in the load current loop. The proposed converter uses integrated magnetics cores to couple the input and output inductors, which significantly reduces the input current ripple and hence greatly improves the power extracted from the solar PV system. The design methodology along with simulation, experimental waveforms, and efficiency measurements of a 4 kW DC-DC converter are presented to prove the concept of the proposed converter. Further, a 1 kW inverter is also developed to demonstrate the converter's grid-connection potential.

“…Stringent international standards such as IEC 61000-3-2 and IEEE 519 impose harmonic restrictions on recent electronic equipment, which have resulted in significant research efforts on PFC circuits [1,2]. Among various power factor correction (PFC) circuits, the single-ended primary inductance converter (SEPIC) has the desirable features of its continuous input current, ripple current reduction, and wide output voltage range [3,4]. To achieve high power density and fast transient response, the SEPIC converter should operate with high switching frequency.…”

A continuous-conduction-mode SEPIC converter with low reverse-recovery loss is proposed for power factor correction. The proposed SEPIC converter can reduce the reverserecovery loss of the diodes and improve the power efficiency. By utilising a coupled inductor and an additional diode, zero-current turn-off of the output diode is achieved. The reverse-recovery current of the additional diode is reduced by the leakage inductor of the coupled inductor. The proposed SEPIC converter provides high power efficiency and high power factor compared to the conventional PFC circuits employing the SEPIC converter. An operation principle and a detailed analysis of the proposed converter are presented. Experimental results are discussed for a 300 W (330 V/0.9 A) prototype under the universal input voltage (90-265 V). It is shown that the efficiency of the SEPIC converter can be significantly improved.

“…The active-clamped SEPIC topology was considered after a detailed comparison of different hardswitched and soft-switched converters. The active-clamping techniques [2][3][4][5][6] as well as SEPIC based topologies [7][8][9][10] have been independently implemented in dc-dc or rectifier applications with good results. It is identified and shown in this paper that an active-clamped isolated SEPIC rectifier ( Fig.1) can meet the rigorous requirements of avionics applications.…”
