The ePix10k x-ray camera is under development at SLAC for use in hard x-ray experiments at the Linac Coherent Light Source (LCLS). It is a lower-noise, higher-maximum-signal autoranging replacement for the Cornell-SLAC Pixel Array Detector in wide-dynamic-range applications. A series of measurements to characterize a prototype system has been carried out at the Stanford Synchrotron Radiation Lightsource...
This paper describes the principles and characteristics of a novel ac-link bidirectional DC-DC converter with synchronous rectifier, which has a mechanism formed from two bridge-type DC converters that are linked through superposition in additive polarity in series. For an isolated dual active bridge DC-DC converter, which has been studied for many years, the rated voltage of its switching elements...
This paper presents performance characteristics of a novel soft switching three phase utility frequency AC (UFAC) to high frequency AC (HFAC) direct converter with PFC function for industrial induction heating and melting applications. The proposed ??simple three phase system?? consists of single phase UFAC to HFAC direct converter in each phase, three phase low pass filter and IH load. This power...
This paper presents a one stage circuit topology for a double buck chopper type single phase PFC converter with active power filtering function in a utility AC grid side and DC output power quality, which can realize much smaller in reactor size and lighter in its weight, along with two unique channel control schemes. The main advantageous point of the newly-proposed PFC converter includes that the...
A single-pole four-throw (SP4T) switch IC with a 3 dB bandwidth of over 50 GHz, which is believed to be the highest among cold-FET SP4T switches, is presented. A miniature and ideal divergence structure with an advanced four-level interconnect provides highly uniform performance in different paths.
Matrix type high-speed optical packet/burst switch is developed that shares high-cost devices for contention avoidance, such as tunable wavelength converters (TWCs) or fiber delay lines (FDLs). In such kind of architectures, there is a technical issue that an overloaded flow causes not only high packet loss probability of itself but also higher packet loss probabilities of other normal flows. We propose...
This paper presents an improved circuit prototype for a buck chopper type single phase PFC-AC/DC converter, which has smaller reactor size and lighter weight, and minimize DC output voltage ripple factor characteristic with two specific loop feedback control strategy. In addition, this active PFC-AC/DC converter can be suppressed the current harmonics in utility AC grid line sensorless specific feedback...
In this paper, we have experimentally studied DC bias depending frequency characteristics of SAW and layer mode and their higher frequency mode, on the hetero epitaxially grown AlGaN/GaN film on Sapphire substrate which is used for HEMT IC. By applying DC bias signal surface and layer waves are generated by depleting 2DEG, which is shortening the surface area of the substrate. In this operation, the...
We have successfully demonstrated, for the first time, a bit-rate tunable all-optical regeneration at 10 Gbit/s, 40 Gbit/s and 80 Gbit/s by using the same SOA-based all-optical polarization switch utlizing one variable differential group delay generator.
