“…For the switch‐resonant converters, they use the resonant tank connected with switches to achieve soft switching. These switch‐resonant converters can be classified into general mode [14–17], full‐wave mode [18–20], half‐wave mode [21–23], active clamp [24–36], zero voltage transition (ZVT) [37–48], zero current transition [49–51], and ZCTZVT [52, 53].…”

“…Therefore, identity of each topology does not resemble the weakness of the design but it can encourage researchers to improve and redesign new converter based on the basic topology. Recent development in SDSR topologies [1][2][3][4][5][6][7][8][9][10] obviously implementing N-Channel MOSFETs for the power switches and the synchronous rectification (SR) switches. Besides, isolated topologies with symmetrical transformer characteristic such as half-bridge, full-bridge and push-pull are also the preferred choice for the SDSR topology.…”

This paper presents an optimized and enhanced DC-DC converter design for 20V output for portable instrument application. The proposed design is based on isolated push pull topology switched mode power supply. Selfdriven synchronous rectification (SDSR) is introduced in the rectification stage in order to create an improved way of rectifying process. N-Channel and P-Channel MOSFETs are used to simplify the synchronous rectification control circuit. Both MOSFETs offer ultra low On-resistance which can be used to achieve higher efficiency than the conventional converter. This converter operates at high speed switching frequency to gain high power-to-volume ratio. In addition, minimum deadtime is set in the design to ensure high efficiency in input-output power transfer. Passive low pass filter is implemented to produce ripple free output voltage in the design. The finalize topology which is push pull with self-driven synchronous rectification is constructed using simple control circuit but maintains good efficiency in its operation. Experimental results show that the proposed converter reacts very well with the self-driven synchronous rectification method. Input voltage is set at 12V and switching frequency is set at 30 kHz in order to minimize the switching stress and conduction losses. Practical implementation of the converter shows that the converter operates at a maximum efficiency of 84.1% and only produces 50mVp-p ripple output voltage which is considered good for a regulated DC output.

“…Consequently, a synchronous rectification framework and bidirectional energy flow characteristics are provided for the converter. Although the switch conduction losses can be reduced by applying a synchronous rectification framework [1][2][3][4][5] to increase the energy conversion efficiency provided compared to that of general boost converters, high dv/dt and di/dt and switching loss problems are continually triggered during switching. These problems reduce the energy conversion efficiency of the converter and may cause severe electromagnetic interference (EMI).…”

In this study, the authors focused on developing a bidirectional power converter for a stand-alone photovoltaic power generation system when a lithium-ion battery is used to regulate the power supply. Also, a small-scale air-conditioner was provided as the load for the bidirectional power converter developed to examine the efficiency of the converter. The overall framework of the proposed system comprised a maximum power point tracking controller, bidirectional buck-boost softswitching converter, lithium-ion battery and small-scale air-conditioner. By attaching a resonant branch to a general bidirectional buck-boost converter and applying a simple switching signal control, soft switching was achieved, thereby increasing the power conversion efficiency of the photovoltaic power generation system. Some measurement results are made to verify the feasibility of the developed bidirectional dc-dc soft-switching converter for stand-alone photovoltaic power generation systems.
