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 ...

Investigation of MOSFET failure in soft-switching conditions
Microelectronics Reliability, 2006Thanks to an ad-hoc experimental test equipment, the reliability of MOSFET devices in soft-switching operations has been investigated aimed to discovering the role of the freewheeling phase in the device reliability reduction. Extensive tests at several temperatures, on-state currents, reverse current peaks, dc-voltages and gate timings have been done,

On soft switch programming for reconfigurable array systems
IEEE International Workshop on Defect and Fault Tolerance in VLSI Systems, 2002This paper deals with the programming and control of non-permanent (soft) switching elements in an augmented interconnection network of a two-dimensional VLSI/WSI array. In particular, it is addressed the issue of cost for programming soft switches involved in the routing process for the interconnections from the primary pad pins. Cost is analyzed with

Switch-mode power converters are used in a wide variety of applications. In most applications, it is desirable to design high-frequency switching power converters to increase their power density. However, the switching losses are increased by increasing the frequency. Moreover, large dv/dt and di/dt produce electromagnetic interference. To minimize the

Soft switching resonant converter with flying capacitor
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013A new soft switching resonant converter is presented in this paper to reduce the switching losses on power MOSFETs and overcome the reverse recovery losses on rectifier diodes. Two half-bridge legs connected in series and two split capacitors are adopted to limit the voltage stress of each MOSFET at half input voltage and to reduce the current rating ...
