The document outlines the history of wireless power dating back to Nikola Tesla's proposals in 1891. It explains the basic principles of Witricity which uses resonant magnetic coupling between transmitter and receiver coils oscillating at the same frequency. Applications are discussed along with advantages such as being unaffected by weather and allowing charging of devices anywhere in range.
Automatic Phase Changer
This document describes an automatic phase changer circuit that can shift the load to an alternate power phase if the voltage drops below a certain level in one of the phases. The circuit uses three identical sets that each correspond to one of the three phases (R, Y, B). Each set includes a transformer, comparator, transistor and relay. The transformer steps down the voltage which is then rectified and used as input for the comparator. The comparator compares this voltage to a reference voltage and triggers the transistor and relay if the phase voltage is low, shifting the load to another phase with sufficient voltage. This automatic switching prevents equipment downtime if one phase loses power.
IRJET- Designing of Single Ended Primary Inductance Converter for Solar P...
This document describes the design and modeling of a Single Ended Primary Inductance Converter (SEPIC) DC-DC converter for photovoltaic applications. A SEPIC converter is proposed to boost or buck the variable voltage from a solar panel to meet load requirements. An incremental conductance maximum power point tracking (MPPT) algorithm is used for better efficiency. The converter output is fed to a sinusoidal pulse width modulation inverter to convert DC to AC for AC loads. The SEPIC converter design and component selection process is explained. The system is modeled and tested using MATLAB/Simulink software and shown to reduce ripple current and provide a non-inverted output voltage compared to other converter types.
Off grid rooftop pv – elsol solar
The document discusses off-grid rooftop PV as an alternative to India's unreliable central grid. It notes India's growing power deficits and shortfalls in capacity additions. Off-grid rooftop PV is presented as a solution that reduces reliance on the grid, transmission losses, and pollution from diesel generators. Key advantages of off-grid over grid-tied systems are also summarized. The document promotes off-grid rooftop PV for non-electrified villages and concludes that rooftop PV growth is inevitable given India's worsening power crisis.
MICROCONTROLLER BASED SOLAR POWER INVERTER
This paper presents the design and the implementation of a new microcontroller-based solar
Power inverter. The aim of this paper is to design single phase inverter which can convert DC voltage
to AC voltage at high efficiency and low cost. Solar and wind powered electricity generation are
being favored nowadays as the world increasingly focuses on environmental concerns. Power
inverters, which convert solar-cell DC into domestic-use AC, are one of the key technologies for
delivering efficient AC power The hardware and software design are oriented towards a single-chip
microcontroller-based system, hence minimizing the size and cost. With this new approach the
modularization of the conversion from solar power to electric power at its maximum power point can
be made more compact and more reliable.
Doc a.7-tlc report
This document is a project report on a microcontroller based traffic light controller. It describes the development of a traffic light controller that uses a microcontroller and LEDs to automatically control traffic lights on a centralized basis. The microcontroller is programmed to adjust the timing and phasing of the traffic signals to meet changing traffic conditions. The circuit uses basic electronic components like an LED for the traffic lights and a microcontroller for automatic signal changing after a preset time interval. It aims to provide a reliable and cost-effective traffic light control solution.
WIRELESS POWER TRANSMISSION -A Next Generation Power Transmission
The document discusses wireless power transmission (WPT) and its history and technologies. It summarizes that WPT was first proposed by Nikola Tesla in the late 1800s as a way to transmit electricity without wires. Current WPT technologies include inductive coupling, resonant inductive coupling, and microwave power transmission. WPT offers advantages like more efficient transmission and reducing e-waste from batteries, though installation costs are currently high. The document argues that WPT will play an important role in addressing growing energy demands and reducing power losses in the future.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

- 2. Generation of electrical energy from the footsteps using piezoelectric transducer
- 3. • Is it possible to generate electrical energy from footstep?? • YES!! • Then how is it possible?? • What kind of methodology should be followed? • Is it really something very much difficult to realize?? • It is possible through piezoelectric transducer.
- 4. INTRODUCTION In this technology there is no pollution terminology. In this case there is no need of man power in a huge scale and it also comes with a very little maintenance cost. So the ROI(return of investment) of the technology is very much effective.
- 6. BLOCK DIAGRAM OF ENTIRE SYSTEM
- 7. BASIC COMPONENTS USED Piezoelectric Generator. AC to DC Converter(voltage multiplier). DC to AC Converter(inverter). Chargeable Storage Device .
- 9. CONCLUSION To develop this system one doesn’t need a very big infrastructure, but a very busy place. Where there is no power, such as in the interior of villages we can develop this system to generate electricity for daily uses. Practically the investment is one time and with a very little maintenance the system will provide enough amount of energy output for a long time.
