Soft commutated soft-two-switch DC/DC converter
2018 IEEE 12th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG 2018), 2018In this paper, an improved structure of an isolated DC/DC converter is proposed. The presented structure achieves soft commutation and soft switching conditions. Soft commutation is gained using a passive-clamp circuit at low voltage side of the transformer.

Soft switching converter with powerlimiting feature
IEE Proceedings - Electric Power Applications, 1999A new zero voltage, soft switching converter is presented. This converter implements ZVS to minimise switching losses and it has special output power limiting characteristics. At a constant switching frequency the output power is limited to a maximum value and power falls at high current and low current.

A Single-Stage Soft-Switching AC/DC Converter without Soft-Switching Auxiliary Circuit
2019 IEEE International Conference on Industrial Technology (ICIT), 2019This paper proposed a single-stage soft-switching AC/DC converter without soft-switching auxiliary circuit. The proposed AC/DC converter only uses two main active switches to execute the input power factor correction and regulate the output dc voltage magnitude.

Single-Switch Soft-Switched Isolated DC–DC Converter
IEEE Transactions on Power Electronics, 2012In this paper, a new single-switch soft-switching isolated converter is introduced. In the proposed converter, the transformer parasitic elements are used as resonant elements to transfer energy and to attain soft-switching condition. The proposed converter does not require output inductor just like the flyback converter, and the transformer core does ...

Switching dynamics of IGBTs in soft-switching converters
IEEE Transactions on Electron Devices, 1995Next generation of power semiconductor devices will be designed and optimized to meet the specific application requirements. Mixed-mode simulations are used to study the carrier dynamics in punch-through and nonpunch-through Insulated Gate Bipolar Transistor (IGBT) structures during soft- and hard-switching conditions.

A New Soft-Switching Two-Switch Forward Converter
2007 IEEE Power Electronics Specialists Conference, 2007In this paper, a new soft-switching two-switch forward converter topology has been proposed. Compared with conventional two-switch forward converter, the proposed converter employs an auxiliary switch and a clamp capacitor to instead of two reset diodes, not only its duty cycle can exceed 0.5 to achieve wide range input voltage, but also soft switching

The switches of three-level dual active bridge (3L-DAB) dc–dc converter under phase shift control may operate with hard working especially when the voltage conversion ratio is not equal to one, which will lead to high power loss and low system efficiency.

A simple soft-switched switched-reluctance motor drive
IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2002A simple soft-switched switched reluctance motor (SRM) drive circuit was proposed, involving only three transistors. The circuit aims to drive the SRM with low EMI and with higher efficiency. The circuit performs soft switching by a simple switching method just like the usual hard switching drives.
