Low loss 4x4 optical switching network
Electronics and Communications in Japan (Part I: Communications), 1980AbstractA 4 × 4 optical switching network was realized which has a low insertion loss and good switching repeatability. Practical optical switching networks are in great demand for optical fiber communication and information processing systems of higher grade and more versatility.

PESC `92 Record. 23rd Annual IEEE Power Electronics Specialists Conference, 2003
A low-loss soft-switching CSI topology, consisting of two parallel switches with a midpoint connected capacitor, is proposed. The structure accomplishes zero voltage switching during turn-off without any additional snubber circuit. It is well suited for high power applications requiring the use of two parallel switches. An analysis and design procedure

Single-stage single-switch input-current-shaping technique with reduced switching loss
IEEE Transactions on Power Electronics, 1999In this paper, a new single-stage, single-switch input-current-shaping (S/sup 4/ICS) technique which features substantially reduced turn-on switching loss of the switch in a S/sup 4/ICS flyback topology is described. In the proposed technique, the turn-on switching loss due to the discharging of the output capacitance of the switch is reduced by ...

Determination of switching losses in IGBTs by loss-summation-method
IAS '95. Conference Record of the 1995 IEEE Industry Applications Conference Thirtieth IAS Annual Meeting, 2002The exact determination of switching losses in power transistors is still an important problem. This paper treats investigations on switching losses in insulated gate bipolar transistors and assigned freewheeling diodes at hard switching commutation. Especially, a new technique, the loss summation method, is presented.

Switching losses of IGBTs under zero-voltage and zero-current switching
PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002Turn-off switching losses of punch-through (PT) and nonpunch-through (NPT) IGBTs under hard switching (HS) and zero-voltage switching (ZVS) are presented and evaluated at 25/spl deg/C, 75/spl deg/C and 125/spl deg/C. A comparison between PT and NPT devices based on their internal device characteristics is given for HS and ZVS.

Improved three switch-active clamp forward converter with low switching loss
2017 IEEE 3rd International Future Energy Electronics Conference and ECCE Asia (IFEEC 2017 - ECCE Asia), 2017The improved three switch-active clamp forward (3S-ACF) converter is proposed in this paper. The proposed converter has minimized switching loss on all switches of 3S-ACF converter by simple change of gate control scheme without any additional components. In addition, current stress of clamp diode can be significantly reduced.

Avoiding internal switching loss in soft switching cascode structure device [PDF]
, 2019 In a cascode switching device, avalanche breakdown of a control transistor and loss of soft switching or zero voltage switching in a high voltage normally-on depletion mode transistor having a negative switching threshold voltage and the corresponding losses are avoided by providing additional capacitance in parallel with a parallel connection of drain-
