“…To solve the problems, soft-switching techniques are indispensable and widely adopted in practical applications. Various snubber circuits are designed to decrease the switching loss and mitigate the EMI problems of the electronic devices [16][17][18][19][20][21][22][23][24][25][26][27].…”

“…The snubber circuits can be generally categorized as the active and the passive types based on whether the active switches that can achieve soft switching are used. A variety of active schemes have been proposed in existing works [16][17][18][19][20][21][22]. For example, a novel soft-switching full-bridge converter with an additional secondary switch and a non-dissipative energy recovery snubber is proposed in [16].…”

“…The auxiliary circuit is composed of a coupled inductor, a converter main inductor and two auxiliary switches, leading to a complex control method. In [19][20][21][22], soft switching of the main power switches is achieved by utilizing various resonance active schemes. Although the switching loss can be significantly reduced and the overall efficiency can be effectively increased such schemes are expensive and less reliable since additional components for active snubber circuits are needed.…”

An interleaved zero-voltage zero-current switching (ZVZCS) high step-up DC-DC converter is proposed for modern photovoltaic power generation systems. The proposed converter can achieve high voltage conversion gain without operating under extreme duty cycles. The voltage conversion gain can be readily adjusted by selecting different numbers of the diode-capacitor multiplier (DCM) cells in the circuit at the design stage. Moreover, with the passive snubber circuit in the proposed converter, all power switches and diodes in the DCMs can achieve zero-voltage turn-off and zero-current turn-on, which effectively reduces switching losses and increases the overall converter efficiency. The operational principles and analysis of the performance analysis with two DCMs are presented for demonstrative purpose. The effectiveness of the proposed ZVZCS DC-DC converter is validated using an 800W experimental prototype.INDEX TERMS Interleaved, passive snubber circuit, ZVZCS, high step-up, high efficiency.

A regenerative-passive snubber (RPS) for pulse-width modulation (PWM) two-switch forward converter (TSFC) is presented. The RPS circuit is recycled the magnetic energy stored in the transformer leakage inductor and is achieved zero voltage switching turn off of power switches. Moreover, the RPS provides the resonant path formed by snubber capacitors and the snubber inductor to achieve zero current switching (ZCS) turn on of switches. In addition, the output diodes turn on/off under ZCS. The proposed RPS-PWM TSFC is analysed and experimental result for a 160 W, 300 kH prototype at the output voltage of 32 V are obtained to verify the theoretical analysis.

In this paper, an integrated of buck and half‐bridge high step‐down converter utilizing single‐stage driving design for high‐efficiency energy conversion is proposed. The proposed converter has the ability to instantly and synchronously transfer energy from input to output within one conversion period. The proposed topology is capable of lowering the primary side voltage of the transformer, so the turns ratio could be reduced. The coupling rate is therefore better along with the leakage inductance. Furthermore, the duty cycle operated in an extreme situation is not necessary. As a combination of the advantages of high step‐down conversion, lower voltage stresses, and fewer amount of semiconductor elements, the feasibility of the proposed topology is verified by the implementation of a 300 W prototype. The proposed integrated topology utilizes the single‐stage energy transfer control algorithm to verify that the proposed experimental circuit has a full load efficiency of 92.4%, in the case of input voltage 380 V and output voltage 5 V, and the maximum efficiency, occurring at 100 W, is 94.55%.
