Design simulation and experimental evaluation of a three-phase controlled capacitor charging type inverter
This paper presents the design, simulation and experimental verification of a new three-phase pulse width modulated inverter. The inverter works on the principle of controlled capacitor charging, where a capacitor that is connected across the load is charged or discharged in a controlled manner to synthesise a desired waveform. The input to the inverter being a voltage source, an inductor is used ...

Novel regulated DC/DC and DC/AC power converters
Power sources with a desired voltage profiles, are required in many applications including renewable energy. Although in most cases, a sinusoidal waveform of specified amplitude and frequency is of interest, other types of voltage profiles, such as square, trapezoidal, triangular, etc., may also be required in amplifiers, shakers, mechatronics, etc., applications. In this paper, a capacitor ...

A new three-phase ZCS pulse width modulated inverter
A novel three-phase inverter is investigated in this paper. All inverters are, in a sense, a waveform synthesiser where the DC at the input is converted to a desired type of waveform at the output. This paper reports the performance of a tracking controller to synthesise the sinusoidal output. Capacitors are charged/discharged in a controlled manner to track any desired waveform with a finite ...

Case study: Wireless controlled, four bar lift, indexing charge feeder
Challenge A unique secondary aluminum producer, located in Kentucky, had recently purchased a more efficient rotary furnace to improve their foundry production. Optimum efficiency requires the furnace doors to be opened and closed in the shortest amount of time to maintain heating efficiency. To feed the new furnace, the current process involved multiple runs using a front end loader to weigh ...

Analysis and design of controlled capacitor charging type power frequency inverter
This paper presents the performance of the capacitor charging type inverters. The inverter uses the voltage and current feedback and produces a desired voltage at the output by suitably charging/discharging a capacitor. An inductor is connected in series to limit the charging/discharging current. Both single and three phase inverters are considered. A small signal analysis is presented to ...

Solar Lighting Basics
How Does Solar LIghting Work? Dawn: The voltage from the solar panel raises and gets higher than it was during the night. When a certain voltage threshold is reached the controller will detect this and turn off the light. The battery will then being to charge itself from the discharge that occurred when it was powering the light. 4 Night time: The voltage from the solar panel is lower than ...

Solar Lights for Parking Lots: The Design Basics You Need to Know
There are a few basic design principles of solar parking lot lights. To gain deeper insight into a cost-effective solar PV system design, here's what you need to know. What is Solar PV System? Solar PV system uses photovoltaics (PV) to transform sunlight into electricity. Solar-powered photovoltaic panels, also called modules, contain photovoltaic cells. These cells convert incoming sunlight ...

Solar Streetlights Are Bright
Solar lighting is being adopted by very many households and they are now becoming a common fixture on streets. They are famed mostly for the savings they bring about in terms of energy bills and maintenance costs and that anyone who uses solar lighting is contributing to a reversal of the damage done by carbon emissions. People know the basics about how these lights work, that is, that the solar ...

The Future Promise of Vehicle-to-Grid (V2G) Integration: A Sociotechnical Review and Research Agenda
Abstract Vehicle-grid integration (VGI) describes various approaches to link the electric power system and the transportation system in ways that may benefit both. VGI includes systems that treat plug-in electric vehicles (PEVs) as controllable load with a unidirectional flow of electricity, such as “smart” or “controlled” charging or time-of-use (TOU) pricing. VGI ...

What’s Your Risk Tolerance during Construction of a Utility-Scale PV Solar Power Plant? Active Stow vs. Passive Mitigation
Utility-scale engineering and construction projects are inherently risky. Large numbers of people independently working on a site, out in the weather, around dangerous machinery large and small, racing to finish the project as quickly as possible. Most Engineering, Procurement, and Engineering (EPCs) in the solar industry have the personnel safety issue solved. There are ongoing, sophisticated ...

Managing Battery Charging - Using Diversion Loads
Tcharge regulation can be relatively simple: When the I-'1/batteries are full, the controller disconnects the PV r array. Adding wind or microhydro to the system makes charge regulation more complicated, since turbines may overspecd if unloaded. Often, diversion control is the solution. Off-grid "hybrid" combinations of solar, wind, or microhydro have been around for decades. These renewable ...

All hail the DuraTrack HZ v3: Best-in-class extreme weather mitigation with array technologies
Extreme weather is a clear enemy of utility-scale photovoltaic power plants. A recent trend of increasingly costly extreme wind and hail disasters reinforces this point, wreaking havoc not only with the actual plants in terms of construction timelines and output, but on the availability and rates of commercial insurance for these properties. In choosing how to fight back, PV plants have two ...

Handyman`s Special!
In January of 1998, Lou Ann and Kelvin Washington were in the market for a new home, away from their hectic jobs in Denver. They found their piece of heaven high on a hilltop in South Park, Colorado. But their new dream home came with some problems, including a power system that was not the best introduction to renewable energy. The house is 2,600 square feet (242 m2), passive solar, and ...
