Dr Jason Sanders (Transient Plasma Systems, Inc.)06/07/2016, 15:30Opening, Closing, and Solid State SwitchesOral PresentationTriggered solid state devices capable of holding off more than 1 kV and surging multiple kA of current are increasingly a viable alternative for pulsed power applications that previously required triggered spark gap switches or other devices based on gaseous electronics. For a number of pulsed applications requiring high surge current at low to moderate pulse repetition rates, Thyristor...Go to contribution page

Heather O'Brien (US Army Research Laboratory)06/07/2016, 15:45Opening, Closing, and Solid State SwitchesOral PresentationThe U. S. Army Research Laboratory has an ongoing program to develop high-voltage silicon carbide (SiC) power thyristors for future Army pulsed power systems. Previously, these SiC thyristors were switched at relatively wide pulse widths to evaluate high-current capability for single pulse events. More recent evaluations investigated minimum turn-on delay and dI/dt limitations while switching...Go to contribution page

Mr Wei REN (Old Dominion University)06/07/2016, 16:00Opening, Closing, and Solid State SwitchesOral PresentationPhotoconductive semiconductor switch (PCSS) is of interest to the high voltage, pulsed power technology and their applications due to its excellent properties of high hold-off voltage, fast response time, low jitter and robust stability. It is known that optical switches have advantages in electrical insulation and flexibility over electrical switches especially for high voltage pulsed power...Go to contribution page

Animesh Chowdhury (Texas Tech University)06/07/2016, 16:15Opening, Closing, and Solid State SwitchesOral PresentationThe importance of non-local effects in impact ionization has been long recognized, particularly in connection with breakdown in gases, where Crooke's dark space and glow striations provide classic examples. The main point is that impact ionization is the consequence of electrons drifting down a potential gradient (i.e., in the presence of a spatial electric field) pick up energy E and can...Go to contribution page

Dr Pavel Rodin (Ioffe Institute)06/07/2016, 16:45Opening, Closing, and Solid State SwitchesOral PresentationSilicon avalanche sharperning (SAS) diodes are capable to form kilovolt voltage ramps with 100 ps risetime for pulse power applications [1-3]. Physics of these devices still remains vague and, as a result, design of the respective semiconductor structures is up to now purely empirical. Here we present the results of comparative study of specially designed and manufactured SAS structures with...Go to contribution page

Lin Liang06/07/2016, 17:00Opening, Closing, and Solid State SwitchesOral PresentationThe reversely switched dynistor(RSD) is proposed by Prof. I. V. Grekhov in 1980s, which is a kind of semiconductor switches applied in pulsed power area especially. Based on the controllable plasma layer commutation principle, Si RSD is famous for its good serial characteristics, low loss and high di/dt capability. It is hopeful to get higher monolithic blocking voltage and better performance...Go to contribution page

06/07/2016, 17:15Power Electronics and High VoltageOral PresentationIn order to meet the stability and high temperature working environment (above 120 degrees) requirement of discharge switch in oil well pulse discharge stimulation device, a kind of Vacuum Switch Triggered (TVS) is developed. Compared with the self breakdown switch, TVS can greatly improve the working life and stability of the whole device. The TVS is designed with multi-rod system to improve...Go to contribution page
