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.

About this Event

Future wireless networks (beyond 5G/sixth-generation (6G) networks)
are envisioned to support 3D communication by integrating terrestrial
and aerial networks. The objective is to provide connectivity to a large
number of devices (known as massive connectivity), to support
substantial traffic demands, and expand coverage. However, effective
resource management in future wireless networks is a challenge because
of massive resource-constrained devices, diverse quality-of-service
(QoS) requirements, and a high density of heterogeneous devices. In this
seminar, I will present my recent research progress which is focused on
communication networking aspects of the Internet of Things (IoT), with
emphasis on algorithm design, network architecture development, and
system-level performance analysis. I will provide a brief discussion on
my three most significant contributions which focuses on the design of
novel algorithms and communication protocols for IoT networks, that have
both (i) enhanced network performance, in terms of spectrum efficiency,
coverage, and energy efficiency, and (ii) satisfied a wide range of IoT
devices’ requirements and constraints. I will then share long-term goal
of my research program which is to develop efficient and low complexity
resource management schemes to tackle the challenges of seamless
connectivity of heterogeneous devices anytime and anywhere. Finally, I
will present my short-term objectives in the next five years which are
to develop resource management schemes for massive connectivity in
future terrestrial networks, aerial networks, and self-sustainable
networks (SSNs) while considering different objectives and constraints,
including network scalability, reliability, latency, efficiency
(spectral usage and energy consumption), and complexity.

Abstract:

In this ever-changing world, it’s important to have the support of someone who could help and guide us to advance in our career. Women are great achievers, but due to the systemic bias, many are unable to climb up to leadership positions in their career. Women empowerment is very much needed especially in these tough times and promoting women by providing platforms where they could build themselves is need of the hour. Here in IEEE WIE, we understand its importance and try to provide such platforms especially to the women in our society who lag behind in their learning path because of many reasons and couldn’t come up. IEEE wants every woman to achieve what they desire to be. We promote not only women but also men who understand and go by our notion.

ANCWT (Advancing New Canadian Women in Technology) aim is to help women with technical skills in engineering accomplish their goals by providing an employment bridging program. ANCWT was established in 2016 and has collaborated with multiple employers in the engineering field. Therefore, the IEEE-WIE, Ottawa, and ANCWT have come forward and took an oath, that we will strive hard to make women gain the required knowledge and confidence to overcome this barrier and find themselves in the background of every picture. Join us on 10th August 2020, in a seminar in which Dr. Sawsan Abdul Majid, President of ANCWT accompanied by two alumni of ANCWT, Oyaje Omakwu, and Dalia Elimam will and take us through their journey with ANCWT in Canada.

Characterization and Modeling of GaN HEMT Trapping Effects for Microwave Circuit Design
Sep 2 @ 11:00 – 12:00

 

IEEE Ottawa Section: MTT-S / AP-S Chapter presents:

Title: Characterization and Modeling of GaN HEMT Trapping Effects for Microwave Circuit Design

Date: September 2nd, 2020

Time: 11 AM (ET)

Register at: https://events.vtools.ieee.org/m/238482

This talk will review some recent advancements achieved on the characterization and modelling of the trapping effects felt in GaN HEMT transistors, and their impact on microwave circuit design. Because of their nowadays importance, a particular attention will be payed to applications on high power amplifiers for mobile wireless infrastructure and pulsed radar applications.

For that, the talk will start by recollecting the most common model formulations adopted for the various levels of RF engineering, from the device level (physics) to the transistor (circuit) and amplifier (system) level. Starting by the Shockley-Read-Hall capture and emission processes we will be able to understand one of the fundamental signatures of trapping effects, the significantly different charge and discharging time constants, and its impact on power amplifier nonlinear distortion behavior. Then, some widely adopted approaches of the channel current transients’ characterization are addressed and the talk concludes by presenting some illustrative cases of application to RF high power amplifiers.
