Proportional-integral (PI) and sliding mode controls are combined to regulate a fourth-order Cuk converter in a continuous conduction mode. A closed-loop system is obtained with the aid of the equivalent control method. Based on the RouthHurwitz stability criterion and root locus, the appropriate PI gains are obtained and a stable and robust system suitable for large signal variations is achieved. The minimum or nonminimum phase behavior of the closed-loop system and the transients of the closedloop system under step variations of various circuit parameters are analyzed. Under a wide range of operating points, the Cuk converter under the proposed controller has a load voltage tracking accuracy within ±0.05 V with a moderate maximum switching frequency of not greater than 100 KHz. The merits and demerits of the proposed controller are compared with some other controllers.

“…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.

“…Simulated and experimental results obtained from the proposed soft-switching SEPIC with multi-output sources are presented in Section 4.Finally, a conclusion is given in Section 5. In general, the soft-switching techniques can be classified into zero-voltage-switching (ZVS) and zero-current-switching (ZCS) techniques [12][13][14][15][16][17]. The ZVS or ZCS techniques drive the voltage or current of the power switch to zero before any switching action, and avoids the concurrent high voltage and high current in the switching transition.…”

Abstract:In this paper, a soft-switching single-ended-primary-inductance converter (SEPIC) with multi-output sources is proposed. The proposed SEPIC has the following advantages: (1) The conversion efficiency can be increased. To incorporate a soft-switching cell with a flyback-type, the power switches can achieve zero-voltage-switching (ZVS) and zero-current-switching (ZCS) features under turn-on transitions, resulting in reducing the switching losses and electromagnetic interference (EMI); (2) The applicability can be maximized. To apply the voltage ratio of the transformers, the proposed SEPIC has multi-output sources with step-up/down voltage functions. Finally, a prototype of the soft-switching SEPIC with multi-output sources is built and implemented. Simulated and experimental results are presented to verify the performance and the feasibility of the proposed soft-switching SEPIC with multi-output sources.
