Abstract:

Application of power electronics is widespread in everyday life. Some applications are considered as “nice to have it;” in other cases, they are essential. This presentation discusses a wide variety of daily-used applications around the world. Also covered is an advanced topic, such as SMART Controller that today’s grid requires for voltage regulation, power factor regulation, unbalance voltage/current regulation, harmonic elimination and so on. A SMART Controller that is based on functional requirements and cost-effective solutions is derived from utilizing the best features of all the technical concepts that are developed until now. Final year students of electrical engineering undergraduate curriculum, post graduate students, researchers, academicians and utility engineers will benefit from attending this course. The participantswill hear from an expert who actually designed and commissioned a fewutility-grade SMART controllers since their inception in the 1990s.

Advanced semiconductor lasers:Ultra-low operating energy and heterogeneous integration with Si photonics devices

Shinji Matsuo, NTT Photonics Laboratories, Japan

Abstract: The electrical power consumed in data transmission systems is now hampering efforts to further increase the speed and capacity at various scales, ranging from data centers to microprocessors. Optical interconnects employing an ultralow energy directly modulated lasers will play a key role in reducing the power consumption. Since a laser’s operating energy is proportional to the size of its active volume, developing high-performance lasers with a small cavity is important. For this purpose, we have developed membrane DFB and photonic crystal (PhC) lasers, in which active regions are buried with InP layer. Thanks to the reduction of cavity size and the increase in optical confinement factor, we have achieved extremely small operating energy and demonstrated 4.4-fJ/bit operating energy by employing wavelength-scale PhC cavity. Reduction of the cost is also important issue because huge number of transmitters are required for short distance optical links. For this purpose, Si photonics technology is expected to be a potential solution because it can provide large-scale phonic integrated circuits (PICs), which can reduce the assembly cost compared with transmitters constructed by discrete devices. Therefore, heterogeneous integration of III-V compound semiconductors and Si has attracted much attention. For fabricating these devices, we have developed wafer-scale fabrication procedure that employs regrowth of III-V compound semiconductors on directly bonded thin InP template on SiO2/Si substrate. A key to realize high-quality epitaxial layer is total thickness, which must be below the critical thickness, typically 430 nm. Thus, membrane structure is quite suitable for heterogeneous integration. I will talk about our recent progress, focusing on ultralow-powerconsumption directly modulated lasers and their photonic integrated circuit. I will also describe progress in heterogeneous integration of these lasers and Si photonics devices.

Bio: Dr. Matsuo received a B.E. and M.E. degrees in electrical engineering from Hiroshima University, Hiroshima, Japan, in 1986 and 1988, and the Ph.D. degree in electronics and applied physics from Tokyo Institute of Technology, Tokyo, Japan, in 2008. In 1988, he joined NTT Optoelectronics Laboratories, Atsugi, where he was engaged in research on photonic functional devices using MQW-pin modulators and VCSELs. In 1997, he researched optical networks using WDM technologies at NTT Network Innovation Laboratories, Yokosuka. Since 2000, he has been researching InP-based photonic integrated circuits including fast tunable lasers and photonic crystal lasers at NTT Photonics Laboratories, Atsugi. Dr. Matsuo is a member of the IEEE Photonics Society, Japan Society of Applied Physics and the Institute of Electronics, Information and Communication Engineers (IEICE) of Japan.

Photonics North 2020
May 26 @ 08:00 – May 28 @ 17:00

On behalf of the conference organizing committee,
we invite you to the virtual Photonics North Conference on May 26-28,
2020.  In the midst of a global crisis,
we look forward to meeting with all of you, our colleagues, as we carry on with
the work of advancing optical science and engineering. Join us for outstanding
plenary talks from inspirational thought leaders. Join us for the very best
work from respected and established researchers. Join us for talks from
emerging researchers, presenting what is surely the opening work of brilliant,
burgeoning careers.

Photonics and optics are finally seeing widespread adoption and significant growth into new markets. Photonic devices are being applied to sensing, communications, and even quantum computing. High speed fiber optics and highly integrated subsystems are essential to the rollout of 5G systems. There has never been a better time for research, development, and training in photonics and Photonics North is essential for developing and promoting the ecosystem.

A Novel Maximum Power Point Tracking (MPPT) Technique for Photovoltaic Solar Panels

By

 

Mahdi Ranjbar

DATE:       July 7, 2020

TIME:        18 19:30.

       

A
novel Maximum Power Point Tracking (MPPT) technique for photovoltaic (PV)
solar panels will be presented.  Current
sensors are costly components. They also require a signal conditioning
circuitry to reduce the noise and condition the signal to be sampled and used
by the controller.  Th
is
method takes advantage of the non-linearity of the I-V curve of the solar panel
to
find the MPP
. By injecting high-frequency perturbation signals and
monitoring the system behavior current sensing used for controlling of MPPT
is eliminated. This elimination can reduce the cost of MPPT circuitry. The proposed method also shows a very fast tracking response due to the use of high-frequency signals instead of relying on low frequency and DC signals which are used in the traditional methods. Numerical analysis, simulation results, and experimental results verify the feasibility of the proposed technique will be shown.

 

Mahdi
Tude Ranjbar received his bachelor’s degree from the University of Tehran,
Iran (2017). In this period, his main focus was on collaboration with different laboratories in ECE and Mechanical engineering departments. He started his M.A.Sc degree in 2018 at Queen’s, Canada with a focus on improving the efficiency of the solar system power generation techniques.  Since March 2020, Mr. Ranjbar has joined the System
Architecture group at HUADA Semiconductors where his main focus is designing power applications using Huada’s microcontrollers, gate drivers and current sense amplifiers.
