Steady-state analysis of soft-switching converters
IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.37243), 2002 Steady-state analysis of soft-switching converters is treated in this paper. Finding the steady-state solution of soft-switching converters by means of start-up transient simulation may involve onerous computations and convergence failure because of the mix of fast and slow natural frequencies determined respectively by the presence of soft-switching ...

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.

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

An improved soft-switching inverter with an unidirectional auxiliary switch
2010 IEEE Energy Conversion Congress and Exposition, 2010In this paper, novel unidirectional auxiliary resonant commutated pole is proposed to improve the performance of the zero-voltage soft-switching inverter. The proposed circuit keeps the advantages of the original soft-switching inverter, while providing more effective resetting capability in magnetizing current.

Soft-switching solid state transformer (S4T)
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016This paper presents a new topology for a fully bidirectional soft-switching solid state transformer (S4T). The minimal topology, featuring 12 main devices and a high-frequency transformer, does not use an intermediate DC voltage link, and provides sinusoidal input and output voltages. The S4T can be configured to interface with two-or multi-terminal DC,

ARCP soft-switching technique in matrix converters
IEEE Transactions on Industrial Electronics, 2002An alternative concept used to avoid the need for staggered switching in matrix converters is discussed. The features of the auxiliary resonant commutated pole (ARCP) soft switching technique are used to reduce the number of active switches and gate drives in comparison to conventional matrix converter technology, avoid commutation voltage spikes, and ...
