Multiple Output Zero-Current Switching Bi-directional Converter
IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society, 2007This article proposes multiple output zero-current switching (ZCS) bi-directional power flow control conversion schemes. This method possesses the conventional features of resonant switched-capacitor converters: low weight, small volume, high efficiency, low EMI emission and current stress.

A new zero current switching resonant Buck converter
2011 24th Canadian Conference on Electrical and Computer Engineering(CCECE), 2011In this paper a zero current switching resonant Buck converter as a soft-switching DC-DC converter is presented In this buck type converter, all semiconductor elements are soft switched. Also, the converter benefits from a very simple control method. Theoretical equations are derived and confirmed through simulation results.

An improved HERIC inverter with zero-current-switching
2017 IEEE Electrical Power and Energy Conference (EPEC), 2017In this paper, an improved HERIC inverter is proposed. It makes most switching devices operate at zero-current-switching state, by only adding auxiliary inductors on the freewheeling branch. Meanwhile, the dead-time is not required and the modulation of the system is simplified.

Zero Current Switching of CFSI using Auxiliary Circuit
2018 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2018High gain inverters such as Z-source inverter (ZSI) and quasi-ZSI are gaining popularity in the applications of renewable energy sources due to limited DC voltage. Current-fed Switched Inverter (CFSI) is a derivative of ZSI, which has similar gain characteristic as ZSI and q-ZSI but with lesser components.

A new zero voltage and zero current power switching technique
20th Annual IEEE Power Electronics Specialists Conference, 1992An outline is presented of work done by the authors on a novel converter topology where the power switching occurs at both zero current and zero voltage, giving it some major advantage over the present state of the art. A description is given of the application of this topology to both high and low-output-voltage converters.

A near zero current switching series resonant inverter using GTOs
15th Annual Conference of IEEE Industrial Electronics Society, 1992The authors present a novel implementation of fast gate turn-off thyristors (GTOs) for a series resonant converter operating above 10 kHz and at an output power rating of 10 kW or greater. A zero current switching gating strategy that eliminates the need of large negative gate drive circuits is presented.

Novel zero-current-switching (ZCS) PWM switch cell minimizing additional conduction loss
2001 IEEE 32nd Annual Power Electronics Specialists Conference (IEEE Cat. No.01CH37230), 2002This paper proposes a new zero-current-switching (ZCS) pulsewidth modulation (PWM) switch cell that has no additional conduction loss of the main switch. In this cell, the main switch and the auxiliary switch turn on and turn off under zero-current condition. The diodes commutate softly and the reverse-recovery problems are alleviated.

A zero-current-switching PWM flyback converter with a simple auxiliary switch
IEEE Transactions on Power Electronics, 1999A simple and effective approach of turning an isolated hard-switched converter design into a soft-switched one is presented. By adding an auxiliary winding, switch and small capacitor to the conventional pulsewidth modulation (PWM) isolated flyback converter, all switches and diodes are softly turned on and off. No extra active or passive voltage clamp
