“…A number of coupled inductor based high step-up converters have been developed, by increasing the turns ratio of the coupled inductor which is similar to that in isolated converters, high voltage gain can be achieved [13][14][15][16]. However, the leakage inductor of the coupled inductor is inevitable, which may cause high voltage spikes and add the voltage stress when the switch turns off [17][18].…”

In applications where the high voltage gain is required, such as photovoltaic grid-connected system, fuel cell and high intensity discharge (HID) lamps for automobile, high step-up DC-DC converters have been introduced to boost the low voltage to a high bus voltage. The voltage gain of traditional Boost converter is limited considering the issues such as the system efficiency and current ripple. This paper proposes a class of hybrid switched-inductor converters for high step-up voltage gain conversion. Firstly, the topological derivation of hybrid switched-inductor converters is deduced by combining the passive and active switched-inductor unit; secondly, this paper illustrates the operation modes of the proposed asymmetrical and symmetrical converters; thirdly, the performance of the proposed converters is analyzed in detail and compared to existing converters; finally, a prototype is established in the lab, and the experimental results are given to verify the correctness of the analysis.Index Terms-Switched-inductor, high step-up, DC/DC converter.

“…Because of the parasitic components of both, the HF transformer and MOSFETs, combined with the fast turn-ON time for the MOSFETs operation, the isolated full-bridge converter experiences a voltage overshoot and oscillations [21]. In the literature, it is possible to find solutions in order to overcome this effect, mitigating these overvoltages and at the same time increasing the converter efficiency [22]. One of them is the clamping circuit, which is implemented in this paper and shown in gray in Fig.…”

Two-stage photovoltaic (PV) configurations have become increasingly popular due to the decoupling between the inverter dc-link voltage and the PV voltage, adding flexibility to extend the maximum power point tracking range. However, the additional dcdc converter increases the power converter losses. The concept of partial power converters (PPCs), which reduce the amount of power handled by the dc stage, can mitigate this effect. However, the type of topology, its power and voltage rating, efficiency, and an operating range can vary significantly depending on the function (boosting or reducing voltage) and type of PV application and scale (micro-, string-, or multisting inverter). This paper analyzes the possible configuration of connections of PPC depending on the application and scale of the PV system and introduces a new buck-type PPC. Three solutions for practical PV systems are further elaborated, including experimental validation. Results show that the PPC concept greatly improves the overall PV system efficiency with the added benefit that the dc-dc stage power ratings achieved are only a fraction of the PV system, reducing size and cost of the power converter without affecting the system performance.

“…During the past twenty years, numerous publications on the development of power-factorcorrection (PFC) pulse-width modulation (PWM) AC-to-DC converters have been published [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In these switched-mode PFC converters, an idea about how to achieve zero reactive power with unity power factor (UPF) in AC source line is often discussed.…”

“…Two classes roughly grouped from the presented PFC schemes are as follows: (1) integration and modification in hardware circuits of power converters [1][2][3][4][5][6][7][8][9]; and (2) application of the developed control techniques to AC-to-DC or DC-to-DC converters [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. The studies in [1][2][3][4][5][6][7][8][9] can be summarized as follows: in [1,2], an additional LC-diode clamper or snubber was integrated into the specified or multilevel converters so that the PFC was completed through the additional clamper or snubber. In [3][4][5][6], an integration of the selected two types of converters or an auxiliary circuit were employed to form a PFC rectifier or converter.…”

Abstract:To efficiently supply wide-range DC voltage from a pulse-width modulation (PWM) rectifier, this paper presents a single-phase, full-wave, diode-bridge, single-ended primary-inductor converter-type (SEPIC-type) power-factor-correction (PFC) rectifier in continuous conduction mode with a sliding surface-regulated current-mode PWM controller. According to the switched-mode operation of the rectifier, a fourth-order switch model of the SEPIC is derived. From the fourth-order model, a simplified state-averaged model which approximately describes the dynamic behaviors of both the output voltage and inductor current is proposed. Then, from the simplified state-averaged model, the sliding surface-regulated current-mode PWM controller for the SEPIC-type PFC rectifier is proposed. The sliding surface-regulated current-mode PWM controller comprises a sliding-mode voltage controller in outer loop for robust control of the output DC-voltage and a sliding-mode current controller in inner loop for phase-synchronized control of the inductor current. For experimental studies, implementation of the proposed control algorithm in a DSP controller and a laboratory prototype of the SEPIC-type rectifier with the DSP-based PWM controller were carried out. Experimental results from the DSP controller-applied SEPIC-type rectifier are illustrated to confirm the validity of the proposed controller for practical applications.
