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.

A New Family of Zero-Current-Switching (ZCS) PWM Converters
IEEE Transactions on Industrial Electronics, 2005A new family of zero-current-switching (ZCS) pulsewidth-modulated (PWM) converters which uses a new ZCS-PWM switch cell is presented in this paper. The main switch and auxiliary switch operate at ZCS turn-on and turn-off, and all the passive semiconductor devices in the ZCS-PWM converter operate at zero-voltage-switching (ZVS) turn-on and turn-off ...

A new family of zero-current-switching PWM converter
30th Annual IEEE Power Electronics Specialists Conference. Record. (Cat. No.99CH36321), 2003This paper presents a new family of DC/DC pulse-width-modulated (PWM) converters, featuring soft-commutation at zero-current (ZC) in the active switches. The new ZCS-PWM boost and new ZCS-PWM Zeta converters, both based on the new ZCS-PWM soft-commutation cell proposed, are used as examples to illustrate the operation of the new family of converters ...

Trench gate IGBTs for zero current switching applications
Eighteenth Annual IEEE Applied Power Electronics Conference and Exposition, 2003. APEC '03., 2004This paper reports on the behaviour of trench IGBTs in comparison with equivalent DMOS IGBTs in zero current switching converters. Extensive experimental results backed up by accurate Spice modelling are presented. These results indicate the superior performance of Trench IGBTs particularly at high switching frequencies, currents and junction ...

Zero-current-switching PWM dc/dc converters
38th Midwest Symposium on Circuits and Systems. Proceedings, 2002An existing idea for a ZCS quasi-resonant converter was extended to generate families of zero-current-switching PWM dc/dc converters. The converter output voltage is regulated by controlling turn on of the auxiliary switch while both main and auxiliary switches maintain the ZCS and/or ZVS condition during the constant frequency operation.

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 Family of Dual-Phase-Combined Zero-Current Switching Switched-Capacitor Converters
IEEE Transactions on Power Electronics, 2014A family of dual-phase-combined resonant switched-capacitor (SC) converters with a similar structure is presented in this paper. Comparing with their conventional single-phase version, each of the proposed dual-phase converters is more than just a switched capacitor but also provides the service of two phases operated in the fully complementary manner.
